The Generation II FIPK is K&N's ultimate performance product, designed to increase power by as much as 10%. Every FIPK is street legal in all 50 US states and comes with a 10 Year/ Million Mile Limited Warranty. K&N 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 allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions).

Good intake, go with something else

The K&N is a good intake kit. It went in easy and it gave me increased turbo response and increased horsepower, but the actual filtration is poor. The AFE intake has much better filtration while still allowing great air flow. Im happy with my K&N, but I will be switching to the AFE very soon
