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 just installed the K & N system on my 2004 4.6 Ford Explorer. My gas mileage has improves around town by 2 mpg & 4 mpg on highway. The throttle response is amazing. I can tell HP has improved. I have a performance rear end so it really moves for an SUV. Next step s to get filter for my 1997 Acura 3.5 RL with only 49,000 miles.
Just a great product.

I put it on my 2013 Ford Explorer Sport Ecoboost twin turbo. Best thing I ever did. It sounds great and definitely has power

Thank you so much for promptly assisting me in getting the carb sticker for my 1995 Ford Explorer. Your staff was extremely helpful and knowledgeable, and certainly made this process simple.
