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]

Product Reviews Review part 57-1002

I added your filter and intake tube to my BMW 325i and am more than pleased. The growl is great and it removed a low down flat spot and added a little more kick but the best bit is it improved my fuel economy by at least 1.2L per 100km, a savings of about $1.60+ per 100km. It will pay for itself in the not too distant future. I have always had a K&N filters in my cars over the years and recommend them to everyone

I put over 70000 miles on my 1995 BMW 325i before I got smart and put in the basic K&N replacement for the floppy OEM filter. What a difference!

A few weeks ago, after rolling over 220,000 miles, my car was in the local BMW specialty shop for a full front to back inspection and tune up. The owner of the shop test drove my car and remarked, when I picked it up, it had more power and torque than any non M type 3 series than he had ever experienced (this coming from a German certified BMW engineer).

He sheepishly admitted to having given it a thorough test drive and asked what I had done to make it so powerful. I replied that all it had was an aftermarket chip and a belatedly added on K&N air filter.

I have, over the years, flogged my 325i up and down mountain back roads and cruised over endless hours of interstate and have never wanted for more power. I still have the same dutifully cleaned and oiled K&N filter too!

Thank you K&N

Before using the K&N Air Filter on my BMW 2002 325Ci I was consistently getting 400 miles a fill-up. Since the installation I am averaging 425. Once I got 445. Plus I got a few extra ponies from the throttle.
