Altitude Will I have any problems with this and the flow master American thunder exhaust going from sea level to 6200ft in CO springs? Or should I get it tuned?

Breakall Year: 2005 Model: GT

  • No problems whatsoever, You'll probably notice a slight power gain going from sea level to 6200 ft as the air being taken in is MUCH lower temperature than the air at sea level. A tune would simply unlock more power than you currently have. Simply put, adding a "no tune required" cold air intake to your vehicle, will not add any power directly. The vehicles ECU is still programmed to pull in a specific amount of air. Having the CAI just allows it to do this more efficiently. Adding a tune to the CAI is what really wakes up your vehicle, changing it's programming to take in more air for combustion and in higher altitudes the colder the intake air the more power you get!

Engine Codes? If I buy this and install it do I need to reset the engine codes. My buddy had a form of this on his 99 eclipse and he said since it was older there was no need for a engine reset. So with a newer car will I need to or just install it and it'll be fine? Also will my engine automatically be able to calculate the extra MPG I will gain?

Tyler18 Year: 2007 Model: GT

  • This upgrade is purely bolt on. There's no need for a reset or reprogramming. It increases the air to the engine. Your ECM will read this and in turn adjust the fuel to air ratio to be optimal automaticly. Now that this has been said, I do suggest a performance programmer such as the American Muscle Bama Tune devices or another like alternative. They aren't nescessary, but they will make a diffrence in responsivness and HP when paired with a CAI like this. You can even find them bundled to sove some $. I could tell the diffrence with mine on muy 2001 GT, and guarantee that you will appreciate it on yours.

    Good addition to stock gt

    I installed this product on my 2007 gt yesterday. There is a noticeable increase in power and the car sounds sick at WOT! I am also seeing an increase in MPG's. Easy install. I definitely recommend this to anyone looking for a little extra cheap hp.

    There was a small increase in power and overall smoothness of the car, however it was less of an increase than i thought it would be. MPGs went up about 1 mile per gallon. Install was about 45 minutes. Hardest part is getting the bolt into the radiator shroud. Overall decent product. Shipping was great!

    No Tune Required is RIGHT!

    My brother installed this for me today - he is a technically adept person who has worked on many of his own cars. The instructions were a bit sketchy in areas and what others said would be a 1/2 hour install was probably around an hour and a half. Immediately, upon driving the car there was a notable improvement in the throttle lag that the automatics are known for. I have to admit, I was quite skeptical about what, I - as the driver - would get out of this being installed, but I have to tell you, it was quite impressive. Before, compared to after, was quite a large difference.

    Very Easy install, good instructions, about 1 hour and you are good to go. The HP gain is very noticeable. Also the fuel consumption improves significantly (highway 65mph at over 30mpg!!!). On every day conditions and kinda lead foot I noticed about 2mpg improvement (from 15mpg to 17+ mpg)
