Review on 🚀 Enhance Performance with the K&N Cold Air Intake Kit: Boost Horsepower, Legal in All 50 States: Fits 1999-2002 CHEVROLET/PONTIAC (Camaro, Firebird)57-3041 by Adam Abner

I saw this item go up to $180 on Revain Warehouse Deals in December 2013. I think I received a return from a customer who left a one star review - happy not to report any issues so far! Installing it on my 02 3.8 Firebird was pretty straightforward, the instructions are illustrated and easy to follow. When I bought the car it already had a Flowmaster Catback, but when it got into the higher rpm range (4K+) it sounded breathless. After I installed the CIA, it sounded deep and throaty throughout the RPM range. I didn't notice any improvement in performance or fuel efficiency, but it was worth just opening the exhaust pipe.
