I have recently purchased a 2006 Chevy Impala LT 3.9L V6 and am extremely happy with the car aside from a few minor problems. The first thing I want to do to this car is install a cold air intake into it, but I have been having problems finding any cold air intake systems that will install into my car. I was wondering if anyone knew of any systems that would be compatible with my car, and also I wanted to know if a CAI system will increase or reduce my fuel efficiency. Thanks for the help!

Thanks for the link suzuki, but is this a CAI or just a regular Intake system?

 

have you looked to see if aem has a system. particularly an aem dryflow tech system. stay away from filters that need oil or recharge kits. they will reduce gas mileage by a few mpgs.
