06-07.5 Chevy Gmc 2500 3500 Duramax LBZ

The 57 Series Generation II air intake, also referred to as an FIPK, is K&N's ultimate performance product.

This system has an extremely high flow intake tube design starting at 6" diameter on filter side going to the 4" turbo side of intake tube, keeping air volume and speed high!

57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with a Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing.


K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable.
