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 installed the 63-2574 on my 2008 Ford150 with 4.6l engine.  I was coming up from NY city visiting my mom.  There was an immediate increase in acceleration from the get go and on my trip up to Toronto I usually have to fill up my 100 liters to make it into Toronto.  This time I had a full 1/4 tank or 25 liters extra.  Not only did I get immediate passing capability my truck was running a lower 250 r.p.m  doing 100-120 kph.  

The instructions were great but I regret approaching 50 years of age that the tiny details of clamping bracket and O2 sensor could use a blown-up diagram to assemble the washer/nut/bolt combos.  Other than this the instructions were self-explanatory. Need those blown up details.  The Cad generated details look as fuzzy on your downloadable PDF installation drawings and I had to resort to a cold beer and trying to read the letters associated with the diagram and the materials list to assemble the two areas of the system.

My only regret is that I was not able to get the system to Canada to assemble it in the truck and take it down to Floyd Va.  for a seminar.  It would have been great to see how it handled on the rolling terrain of W. Va and Va.  

I am very impressed with the FIPK kit and would not hesitate to do it again or recommend it to my collegues and friends.  A small price to pay for such a difference in performance and helping the environment by saving gas.  Within two years I will recoup my initial investment and put 10% less pollutants/fuel by-products in the air.

I have used K&N Filters in all of my vehicles for the past ten years.  That is one of the first things I change when I purchase a new vehicle.

I just purchased and installed the K&N Cold In-Take system for my 2007 Ford F150 4x4 4.6L.  This is the first Cold In-Take system I have ever had... but am very pleased.   I will have to update this later for the hopeful improvement in my gas mileage... but I can tell you I noticed an immediate improvement in power... and it sounds nice as well.  It is amazing what a difference it makes.  

I will also have to give kudos for the instructions.  My total install time was about 45 minutes and it couldn't be easier.  The part matched my truck and everything fit just like it was supposed to... Thanks K&N!!!!

I brought the K&N aircharger (63 series) with air wrap for my 2007 Ford F150 (4.6L) and what a difference it makes in all around performace.  Not only does it increase throttle response it has improved gas miles too an extra 2 miles per gallon.
