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).

1998 Cummins
Location: Millville,PA
Noticed quicker throttle response and power; as far as fuel mileage that will be determined later (wasn't looking for that really anyway).
Great Product overall

Putting the rubber heat shield on was a bit tricky. Also getting the old presure sensor off the old stock intake was an escapde to say the least. But its not K&N fault. Great product after working the kinks out took about an hour to intall fully. Very heavy duty and snug would recomend bolting the housing down...But once it was installed I notices a slightly higher idle, Alot better acceleration and a turbo wistle like no other when running. Also gets 2-3 better MPG, Great product and super fast shipping. Thanks XDP and K&N.
Easy to install great product

I installed my intake today and installed it in about 10 minutes it came with everything needed. I went for a test drove and noticed more whistle and power. Great product.

How does this filter do in moderatly dusty conditions?
View Staff Answer 

Our testing has demonstrated that on average, K&N replacement air filters and air intake systems have a cumulative or Full Life filtration efficiency of between 96 and 99%. Different filters test at different efficiencies due to changes in their shape, surface area and relationship to the direction of air flow through the factory air box or test housing. Like most air filters available in the USA, our filters will provide all the engine protection you need.
For more information on our testing, see our K&N Product Testing page.
