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]

 I wish I'd put the KN air intake system on my 2001 Ford Ranger 11 years ago.  Although Ive always liked the truck, I'd always been disappointed in the 2.5 liter's throttle response.  Now, with the air intake system installed, my truck actually responds to the throttle like it's supposed to, with no dead spots at any time.  I can't recommend KN highly enough. Thank you.

  Hello all @ KN,

I just wanted to take a little time to contact KN and say thank you for such a great product. Since buying the complete air intake system I have seen a huge difference in the performance of my 1999 Ford Ranger 4.0 Prerunner. I will always use the kn product in the future with all of my vehicles now that I have seen how a KN filter helps the performance of my Ranger. I will also highly recommend it to anyone who will be looking for a quality air filter going forward.
