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).

Love it!
I have a 02 Dodge Ram 3500 bought this months ago first time installing and it was easy makes my turbo whistle louder.
Works well does not fit well
I put this on my 95 12v 5 speed truck, that truck is stock besides a turned up afc and a straight pipe, the turbo is much louder and I do notice a smoother acceleration, when I went to instal the new air box I noticed it was hitting the top of the shock stud and wouldn’t allow it to sit where it should, the factory plastic nuts don’t hold the box anything close to snug, they also provide a small bracket to support the air filter against the fender, the hole they provide is much smaller then the bolt they tell you to use and the bracket is about an inch and a half off from lining up, so after cutting the top of the shock off, taking out the inner fender to use nuts and bolts to hold the air box down, making my own bracket to support the filter and replacing a hose clamp with one you actually tighten, it works great, for 330 I would expect alittle better than that
great product
I would recommend this product to anyone the performance is better, the mileage goes up a little and best of all the sound you can hear that turbo spooling up. people who don't even know what a diesel is ride with me and that's what i get commented on the most.

Questions and Answers

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.
