i received the filter... installed it, first time closing the hood it actually pushed the hood up a tad bit... i stepped back and said... ya kno that doesn't look right lol, so than i opened the hood, loosened the intake clamps and kind of made it all super tight so i could slip the filter down more... it worked, no CELS or anything showing so i suppose the IAT sensor and other's are ok... i did however put the AEM up against the K&N and yes their is about a 1-1½ inch different and the K&N is wider by a tad. however the car run's better, mpg's improved a hair and it has that good ol' breathing sound when ya get on it... i 4got how much power the mtx cougar had. i don't knock on cougars either. some guy's have them around here and i've seen one take down a type s rsx... those k20a motors are vicious also... my last request i suppose is can a mod. shut down this thread it is no longer needed, and thank you everyone for your support
