"I like it, looks good and it sounds good at high revs, although not as loud as they claim. I can now also hear the knocking of the engine. The instructions could be clearer, I suggest that you study the exploded diagram first, the pictures on the brochure are small and in black & white and low resolution, I would have like better instructions. Overall I think is kind of expensive it should be at least in the 200.00 range to match the value." —Jose N from Conover, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Pontiac Grand Prix, 3.8L V6.
