I have a Mazdaspeed3 2008 and I just installed the AEM cai and it runs incredibly!!! I was amaized of the instant power that you receive under the wheels. Oh and by the way this last Sunday night I beat the heck out of a Mustang Cobra I believe the Cobra model was a 2005. I have more mods installed but still!!! and my car is only a 4 cylynder!!!!

Problems with installation

Kind of a pain to get the air filter on because you have to go through the wheel well and the fit was pretty tight and took alot of small tweaking to get to fit right. If i can improve anything it would be just to have the air filter shoot straight down rather than having a bend for the air filter to fit in the wheel well. That should cut about an hour off of installation time, if you are doing it by youself. Other than that, I've had an increase in horsepower and gas mileage. Not to mention you can hear the intake working, especially with a turbo. Overall quality is excellent will be buying AEM products from now on.
