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). [MORE]

Hello

Just want to say how great your filter is. I installed an air intake kit for my 2010 Ford Focus. The car itself is a great little car with a 140 hp inline 4 cylinder engine that gets great gas mileage, and your kit made it even better. During the 1st test drive with the kit installed I immediately felt a noticeable improvement in performance it accelerates faster, and shifts quicker. When I filled my tank up a week after installing I noticed that I gained an extra 65 km out of it.

Will use kn filters on any future vehicles I own.

Hi,
Just like to say thank you guys so much for the quality that you provide. My old ford Focus from 2000 can now drive an extra 30-50km on a tank and went from 75hp to 83hp :) Greatest investment ever!!! Especially since the gas price has gone up to 1.66 Euro/Litre here...

THANK YOU!

I just installed a K&N High-Flow Replacement Air Filter into my '03 Kawasaki Vulcan 800 Classic and can already tell the difference.  Both acceleration & throttle response seem to have significantly improved.

When my '98 Ford Taurus SE Wagon was nearly new (at 11,053 miles), I installed a new K&N Air Filter. There's now just shy of 260,000 miles on this filter and after more cleanings than I can remember, it's still going strong & working perfectly.  I now also have K&N Air Filters in my wife's '02 Ford Focus and my son's '01 Toyota Corrolla.

I won't have any other air filter in any vehicle I own.  Sure, they're initially a bit pricy, but they will pay for themselves over and over again.  Put one in and you'll never regret it.
