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 K&N's 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 air filters on these kits are washable and reusable. Most of our air intake systems are easy to install using tools commonly available (see installation instructions). [MORE]

Easy install. Great upgrade to my 2014 Ford F150 Raptor.

I had to share this with you guys at K&N,,I have been asking a lot of my friends about this filter system and there was a lot of doubts in people's heads if this was a sure thing,,,well let me tell you, I bought the best one chrome tube system and my throttle response is a lot better. My gas mileage has increased 30 to 40 per cent more. If I kick it at 30 ,,it spins the tires. 1997 Ford f150 with a 4.6. This has to be the best unit I could have put on my truck. It took all of one hour to put on and I could have done it quicker but I like putting it back as close to the original as possible. It sounds like a deep throat with no bottom to it. I love it and will recommend this to all of my friends from now on,,really bad ass set up. At 60 years old I feel like a reborn gear head again. You know what they say,, You are only old as you feel,,21 again,,,

I have been using K&N filters since about 1968 starting with my dirt bikes.  Use on all my vehs since.  I have a 1995 Ford F150 with a 302 and a 1997 Jeep Grand Cher with a 4.0 and both have K&N air filters.
