The 57 Series Generation II air intake, also referred to as an FIPK®, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 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. Most of our air intake systems are relatively easy to install using tools commonly available (see installation instructions).

Good performance, but quality/fit lacking

Overall, I'm a big fan of K&Ns proven performance. I was a bit disappointed in the fitment. The filter housimg is flimsey and does not fit tight, there is a 1" gap between the rubber gasket and the fender. As far as a "cold air" intake, this is far from it, ther is large gaps and too much open to the engine compartment, which will inevitably draw hot air in.
With that said, I did see some performance increase as I would have expected with greater air flow. I just wish K&N wasn't so cheap on their design.
caused check engine light

I've always had great experience with K&N but not this time on my DuraMax. 60 miles after installation caused check engine light. Dealer diagnosed code P0101; a mass air flow sensor code. Reset it twice; came right back on. Got K&N warranty involved. They were great. Refunded my money with very little hassle. Replaced my stock system and after driving 70 miles; shutting down and then starting back up, check engine was gone. Wish it would have worked.
