K&N 2005 GTO Induction Package

$329.99

Sister product to our 57 Series FIPK, our 63 Series Intake Kits or AirCharger^® Intakes are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone. They enjoy a faster speed to market than our 57 Series kits due to their pending CARB status. These intakes use only non-metallic rotationally molded tubes that can reduce intake air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 63 Series Intake Kits are not legal for street use in some U.S. states.

63-1099 Product Specification:
Product Style: 63 Series Aircharger Kits
Estimated Horsepower Gain: 18.54 HP @ 5818 RPM
Replacement Filter: RF-1048

K&N 63-3092 AirCharger Air Intake - 2016-2018 Chevy Camaro SS

$349.99

The K&N 63-3092 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on specific Chevrolet Camaro SS models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points.

K&N 63-3099 AirCharger Air Intake - 2017-2018 Chevy Camaro ZL1

$549.99

The K&N AirCharger 63-3099 air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Camaro ZL1 models (see vehicle applications). K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Camaro ZL1 engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-3099 air intake tube is made almost completely out of ultra-lightweight carbon fiber. Included is a K&N high-flow air filter and a heat shield that directs cooler air into the custom molded intake for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N Aircharger "Typhoon" Cold Air Intake Kit- 2016-2018 Camaro SS 6.2L

$399.99

The K&N 69-4534TP Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit specific Chevrolet Camaro SS models. The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon air intake which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intake. More air means more usable power and acceleration throughout the engine’s RPM range. In addition to more power, this air intake system improves engine sound with more aggressive and deeper acoustics during acceleration. Included is a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive silver powder-coated finish that's made to last and it accommodates the factory mass air sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a couple of screwdrivers, a ratchet set and several wrenches.

$349.99

In the K&N tradition of engineering power, K&N Performance Kits are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range, with even greater power gains in turbocharged and supercharged engines. The filters on these kits are washable and reusable.

David K.

RYAN D.

Second time I’ve used mail order tuner on this Truck. Did a bigger cam 8 years ago. Ran great with that tune. Now I replaced the engine with the summit 5.3 450 hp crate engine went with bigger injectors . Runs and tows great.

Jeremy K.

Just finished a 6.0 swapping my c1500. The ecu worked great.

Casen L.

Ive used this tuner several times and he does a great job! I plan on using in the future for my other projects!

Kelly P.

Great experience. Tune is perfect, and Casey helped me diagnose some other issues I was having, too. Will definitely use again. Highly recommend.

Truck started right up just wondering if you guys did anything will the the transmission shifting?

Bought a 260k mile ltz suburban in great condition other than a collapsed lifter for $3800. Swapped to a fresh rebuilt l83 with low lift stage 2 cam and many other improvements. Sent in ecu with list of work done and got it back right on time. Truck ran on first start, runs very strong, retained flex fuel and is returning 15.5 average mpg with 21 mpg max for 50 miles since swapping to 0w20 oil after break in. Easy process, great results!

All done to the ‘T’

The people over here are great ,very knowledgeable, and the women on the phone,extremely friendly and very helpful when I called and had questions. Finally purchased a HP tuner MPVI4 thanks to the secretary’s recommendations, now it’ll be much easier to work back-and-forth with casey which does very good work by the way. Also, my customers will be even happier.

Bryan G.

Did a 6.0 swap in a s10 blazer . I use them to get running and a shake down before going to the dyno and get tune . thus saving me time . There tune is very close I mean very close, only thing i see that could be better is they are a little shy on WOT shift points.. probably a CYA thing...I have used them 3 times now and are Much better than most so called tuners out there.. YES worth the money the best mail order tune you can get, For the ones that don't have axes to a tuner this is the only one I will recommend........

Noah S.

Was very informational and made sure if exactly what ibwas looking for and received it back very quickly I will definatly use them again on my next project .... Thank you very much

Matthew S.

I was so glad I was able to utilize your service. I would have had to have driven a significant distance to get to a tuner so this was definitely a blessing. I definitely recommend to anyone considering using this service to definitely give it a go. I don't think you'll be disappointed.

Brian K.

A very good experience. My computer was retuned quickly and accurately.

Adam H.

Great job. Called me with any questions to make sure took everything into account.

Logan S.

1999 Camaro Ss. I did longtubes, ory pipe, TSP cam. Mail the ecu off on a Tuesday got it back the following Tuesday. Car runs great. They were quick to respond to questions. Overall a really good experience.

James G.

I did a DOD delete on my 2017 GMC Sierra with parts purchased from Texas Speed. My mechanic had a local tuner come to his garage to tune the truck, they could not get it tuned. I thought I had ruined a very nice and well taken care truck. Texas Speed recommended mail order tuner. My truck is now running like the day I bought it, I was in complete shock when I started it. I couldn't be more satisfied.

Nolan C.

Top notch everything when it comes to dealing with mail order tuners. They are simply second to none.

James s.

This was fast and easy. I mailed my ecu and less than a week later received it back. The truck runs very well now. Thank you

Henry W.

Mail Order Tune did me great. I sent my computer, they received it and went to work on it. I kept track of my computer and knew when it was delivered. Less than 24 hrs after they got it, I got a call from Casey who asked me a couple questions then told me he was starting on my order and it should be done, packed and on its way back to me by the end of that day. Bad weather hit and slowed delivery but, I still had it in my hands 5 days after talking to Casey. I installed it 2 days after I got it back and hell yeah It started. MOT got me going. I am so happy that I stumbled on to MOT and trusted them. Couldn't be more happy and grateful to them. H. Williams, southwest Missouri

David F.

Worked perfectly after crankshaft relearn. Performance is top notch!

Lukia R.

I love the tune. If I could I would make a few changes but I love the way the truck runs and feels .

Super Nice company to work with, i had a ton of questions and he answered every one. Would 10/10 recommend them. The truck sounds amazing after dod delete and stage 2 cam, chops really hard once it’s warmed up. Very happy with my tune. 2019 gmc sierra 1500 5.3

L Carlos E.

Thank u, thank u, thank u. Once I received the engine control module I installed it, went for a 20 mile round trip test drive and lord lord lord. It performed and then some. I rebuilt the motor with a Brian Tooley DoD delete kit. It runs like it never has before. The guyz at Mail Order Tuner came through big time. They actually will talk to you on the phone which is above and beyond. Kudos. I am trying to convince the old lady to put twin snails on it, if she does I will be contacting Mail Order Tuners again.

Andrew S.

They did a excellent job. I had two people do a tune and both didn't work. No power no response. These guys did a perfect tune. And fixed the speedometer and shift points with it big tires and the 4.56 gear. This tahoe runs and drive exactly like I wanted it to. Thank you

David S.

4.8l with NSR Chopacabra! Sounds amazing and runs great!

Carl S.

I haven't driven it yet. Putting weatherstrip on doors. Probably finish this weekend. But it starts great and sounds different in a good way. I know that it's from calibration for the larger injectors. Looking forward to seeing the new shift points. I've told several people about you calling me to ask about what I wanted to accomplish with the tune while you were working on my ECM. I know that it's going to be great having done business with you before and your taking the time to help me with some issues that weren't related to the tuning of my components. Excellent experience.

Willie M.

Nailed it straight out of the box

Chris H.

worked out well

Jose

Tune needs adjustment

burt c.

Did exactly what they said they would

Michael P.

I had my Trans Am mail order tuned a couple years back by MOT after installing a TSP cam. The car runs phenomenal after the tune and I couldn’t be any happier. I highly recommend using MOT for tuning your LS. They also have great consumer service. Really appreciate everything they did

Steve B.

Runs good and shift ok but there is no long term fuel trims.

Paul P.

Turn around was quick and the motor started up without issues with no CEL'S, will be going back for further tuning in the future.

brett h.

This is my first ever LS mod and if I had known it was that easy to get my truck tuned after the chopacabra cam upgrade I would have done this years ago thank you mail order tuner

Don H.

Great personal and good communication.

Valerie P.

Totally satisfied!! I’m very pleased with the excellent customer service and quality work! Thank you again will do business again Mail Order Tuner!

Nick H.

Awesome service and great communication. He took the time to call me and go over the issues I had and was able to fix some things that another "tuner" had screwed up. Had my PCM back in only a week after I sent it out, plugged it in and my truck runs better than it ever has. Highly recommended!

Lamond B.

Great service love the tune

Anthony B.

Helpful, fast, and very knowledgeable

William B.

Night N day difference! Tuned for my Chopacabra cam, 33" tires, 4:11 gears, and delete the infamous AFM. My goal was a dependable daily driver with a little added power. After the tune 5.3 ly5 screams. Now that there's a noticable power increase, I feel compelled to add a Corvette servo and shift kit to my 4L60E to prolong its life and handle the added power better. My 5.3 no longer throws any codes at me. Runs perfectly!

DARREN H.

Car run great and sounds awesome thanks again!!!!!

Jason L.

Perfect tune

jerry b.

It runs good has a small flat spot after shifting but started right up thank you

Bryan L.

Received ecm back after few days, plugged in and everything was perfect. No issues whatsoever so ever

Jeff J.

Was straight forward process to fill out order form . Came back with in the week and worked perfectly. I will be using them again thank you

Zachary H.

Quick and easy shipping and receiving. Have not got it back in the car yet but it will be ready to go. Thank you!

Brian S.

Quick turnaround, no issues, vehicle fired up and hasn’t had a hiccup.

Jason M.

Runs flawless, nice power and sound, thankz

wendall s.

My sierra 1500 5.3 with AFM number 4 cylinder lifter crashed and took out cam was hesitant about putting TSP stage two cam kit in but glad I did the tune that MOT did is wow and service was very fast now my sierra really is the bad ass edition thanks again Mail order tunner

Scott I.

The hardest thing about the swap was everything I had to do. The tune was easy. At first I was feeling a little unsure about the tune, feeling like I had some issues with responsiveness and power, but it turns out everything that was wrong had to do with my work and not the tune. Once I got the truck sorted out, the MOT tune was amazing. My truck is now smoother, higher revving, and harder pulling than I ever thought possible. Unfortunately, I’m now craving more power and I’ll send my ecu back in to MOT once I do more work on the engine.

Blayke V.

Works fantastic, no CEL

Jeremy D.

Super fast work. Communication was impressive. Will absolutely be sending it back here after upcoming upgrades.

Joe A.

Works perfectly! Thank you

Scott J.

The Mail order tuner crew knows what their doing. I have had multiple pcm's tuned and they all turned out great. My 1966 c10 with a 6.0 and 4l60e has been running for years without any issues. Recently installed a 6.2 and 6l80e installed in my 1977 k10. This thing hauls ass with a sloppy stage 2 cam, longtube headers, and a mail order tune. Mail order tuner rocks!!!

dustin p.

very quick turnaround. does everything i needed it to do. love it!

Ayden H.

Texas speed Chopacabra cam working great thanks to this tune. Highly recommend

Micheal B.

greg w.

The folks here are so helpful in many ways! They assist me with the process and what is needed for your tune. Will be a returning customer.

Greg M.

Cranked up first try. Seams to be dead on. Runs very well. I am very pleased with the service. Thanks again

Stephen C.

I could not have had a better experience with having my Truck's ECU reprogramed to delete the AFM program and work with installed delete kit. The folks at MailOrder Turners are awesome. One day turn around, WOW. When I thought I had a problem with turner when reinstalled, I called Casey, we discussed issue, he said send it back. He checked it out, no issues and even sent video of ECU running on a truck at the shop. Highly Recommend MailOrderTuners!

Alan F.

Worked!

Xavier C.

All work out fine . Thanks

nick k.

Very fast turnaround. Great communication.

Matthew O.

Such great customer service! 10/10 would highly recommend to anyone!

Bryan G.

Did a ls swap in a 1988 s10 blazer. Not done with it yet, but it starts right up and idles takes throttle .. So far so good...

Dan R.

I dropped my PCM off at the UPS store on a Thursday at 3:00 thinking It would be awhile before I got it back. It arrived back on my porch less than 48 hours later. It took me some time to get the engine ready, but I installed the PCM today and my brand new engine fired instantly, settled to an idle and drove down the street. No drama, no check engine lights, and runs like it should. I haven't driven the truck much yet, but so far I'm very happy with the service. Thanks

Devin M.

Took care of the check engine light and gets better fuel mileage already!

Brandon W.

Runs great and sounds amazing. The crew at mail order tuners are amazing people and get you what you need and want. I had some small hiccups on my end and they still called me back to help me figure out what I needed to do. When I’m ready for more power I will definitely be contacting them back. And recommend every one I know to use them for there set up.

Oliver M.

Quick

Heinrich T.

Truck fired up as soon as fuel rails filled up. Truck runs and idles great. Transmission shifts perfectly. However my rear o2 sensors are still reading even though they were supposed to be deleted for long tube headers which now causes a check engine light.

Lance B.

Great work!my car ran like Sh** after a cam install got my computer in the mail and now it runs about as good as stock with a good chop !

Travis N.

Fast and accurate. Definitely would recommend using this company!!

Steve H.

They did a great job on the cam swap tune. I had some follow up questions and they didn’t hesitate to help me out! Great place to do business with! Thanks again!!!!

Harold C.

Totally satisfied will definitely recommend and be a repeat customer ✊

Always great working with Casey. Got my Escalade dialed in and sounds and runs awesome!

Donna C.

Service was great and fast! Worked perfect!

Jason M.

Casey has tuned my built Escalde and now my supercharged Corvette and I couldn't be happier. The turn around from sending in a data file and then getting the tune has always been very fast. I first did an N/A exhaust only tune and the car was very fast and drove so much better than stock and then I did a supercharger and the tune is fantastic. If you're not privy to HP Tuners, watch his videos on their website.

Peter K.

Awesome fast and knowable service

Marshall A.

Great tuning and overall communication. Second time using them and will continue to as needed.

joe v.

Mailorder tuners did a Great Job tuning my stock 2016 corvette! It was like going from a wimpy Volkswagen to a fun driving rocket ship! Thanks Guys I love driving this car now! Joe V

Andy N.

Very helpful. Very knowledgeable. Fast service.

Greg T.

I had a few issues on my end, Casey helped me figure them out. Turned out great!!

Steve H.

I got the ecm back after the adjustments and everything is working great! Thank you very much Steve Hight

Edward

Love it. With this when your having problems with how its running you can data log it, and take it to your tuner or mechanic. Especially with those pesky intermittent problems

Jeremy H.

Casey did a great job with the retune on my 2010 Camaro SS after I installed TSP Headers, X-pipe, and high-flow cats. Car runs great and definitely feels stronger.

James R.

amazing service and top notch talent!!

Victor B.

Excellent place to do business, very helpful. And informative all around excellent work

Jose C.

Amazing

Wayne P.

Casey had been patient with me and been very helpful in finding a vacuum leak on my intake manifold. Dialed the truck in and very satisfied. This is my second time tuning a vehicle through Casey and he does not disappoint. Highly recommend!!

gerald e.

Always a quick response. And when they're is something not right they let you know. I've dealt with other tuners who will try and mask mechanical issues. Casey let's you know when something isn't right.

gerald e.

Great

Brian M.

Casey has been very helpful with my tuning. After learning trying to tune myself, it was great to find Mail Order Tuners.

Tanner D.

I have a 2005 GMC Canyon with an LS 6 L swapped in it with a truck noise cam the tune quality is very well very fast turnaround truck runs very well would highly recommend

tim t.

Great service. I mad a user error and they offered to help under warranty just costing me shipping which I’m very thankful for. Good service and great product in regards to tuning success.

Blake L.

The team over at Mail Order Tuner’s has the best customer service, hands-down. They have gone back-and-forth with me trying to get the motor tuned in my truck after we swapped a bunch of parts and a computer. Casey stuck with us the whole way. In the end result was an amazing running truck with an excellent tune. Highly recommend them for anything LS, they will be the only ones tooting my truck for as long as I own it!!!!!!

Michael M.

What more can I say that has not been already said!!! Unfortunately I can only give 5 stars, WISH I COULD GIVE MORE!!! I've been to 5 other tuners, NOT 1 tune has performed better than MAIL ORDER TUNER!!! THANK YOU Casey and the MAIL ORDER TUNER family for their KNOWLEDGE and EXPERIENCE!!! I WILL NOT TAKE MY 2015 CAMARO SS 1LE LS3 416 STROKER ANYWHERE ELSE FOR MY TUNES!!! THANK YOU, MICHAEL

Matthew M.

One of the best LS tuners, very helpful and knows what he’s doing

Tyler S.

I’ve done a few retunes so far on my 01 Tahoe and I’ve loved it all. From fbo to cam and heads, I’m truly grateful to Casey and the team for their patience and help with my NA build this past year as well as all that is yet to come.

Josef B.

Casey has been amazing! He's helped get my 58 Biscayne up and running beautifully! Very knowledgeable and wouldn't take my tune anywhere else!

Coby H.

Customers happy with truck, tunes always on point. Always satisfied with results.

Harry W.

After a marketplace tuner screwed my tune trying to fix my idle, the people at mailordertune really got my car running strong again. Thanks again for the awesome work.

Clayton D.

Solved the problem!

Dave M.

seems to work fine. idle is around 850 as requested. have not driven it a lot with the a/c on so hopeful it will not stall at idle in that condition. I was under the impression I would get the total retune fee refunded due to my requesting the 850 idle speed but casey guaranteeing that 800 would keep it from stalling?

Harry W.

Great people to have tune your car. Always have time to answer questions. I’ll definitely use them in the future for other projects.

Heinrich T.

Sent PCM in for retune after the O2 sensors were not turned off on the initial tune. Turn around time was great and retune fee was promptly refunded. Truck runs even better compared to the initial tune.

BlackPanther M.

Tell them your specs ship and plug it in that ez if u have a problem call there grate

Tim B.

I've dealt with Casey for over 10 years , numerous Ls builds , computer after computer , he will get it tuned , and the lady that does his customer service and keeps everything straight up there is top notch !!! Tim Boone

Great customer service

Keith K.

Had the computer tuned and then changed injectors due to a hesitation. sent the computer back and had it retuned and works perfect. Great company, they know what they're doing. Glad to use them again.

Shaun B.

Put the truck norris cam in and had it tuned and loved it, but i know i wanted headers so i sent computer back to get it retuned and OMG this thing came to life. Everywhere i go people cant believe it. And it gets down and boogies. I am smiling all the time. Thank you very much for doing the part that i have no idea what to do.Verry happy Shaun Brophy
