I just picked up a 2010 GT and I am a newbie to the S197s. How does the factory CAI measure up to the aftermarket ones? Am I better of sticking with the factory set up and replacing the filter with a K&N or should I replace the entire system? If so what systems do you guys recommend? Thanks?
CAI will give you some HP but you won't get the full benefit unless you get a tune to go along with it.
Steeda and C&L are very good.
The steeda unit incorporates the scoop in the bottom of the air box like the factory unit so that it catches cooler air from behind the bumper/grill area.
