K&N's 77-2579KTK High-Flow Performance Air Intake was designed especially for Ford F-150 SVT Raptor Pickup Truck models.

Best $300 I've ever spent... Great sound with my Magnaflow mufflers. It really improved throttle response. Not sure about the mileage improvement... I spend too much time standing on the pedal :-)

My sons and I just finished the easy installation and improvemnt is ridiculous. Throttle response is significantly improved, noticeable bump in acceleration (especially off the line), and the great sound really adds to the driving experience. This is the third truck where I have added the K&N cold air intake and the quality has been consistently great. I challenge you to find a performance upgrade that has more bang for your buck...$350, one hour installatiojln, and +20 bwhp...I am a huge fan. Thanks K&N.

Excellent upgrade. Good quality and so easy to fit with just the limited tools I had on hand. Probably took me 90 mins in total. I bought a K&N air filter for my very first car in 1980 and I would recommend K&N over any other product. On my Raptor it would appear I am now getting better fuel mileage with the K&N performance kit installed. Even though I am accelerating slightly more aggressively. Why? Because I can and it sounds great.

Thank you K&N for the easy step by step directions & your great engineering to make this cold air system a breeze even for a layman to install! Everything went smoothly. It certainly has added some extra ZING to my ZANG! Ed Pensyl

This was installed on my all stock 2012 Raptor SuperCrew. Ordering from K&N was very easy and the item shipped/arrived quickly. Installation was fairly straight forward and simple but a little time consuming for me. Mostly because I'm paranoid and check everything 10 times before proceding, not due to K&N. The only items I wasn't a big fan of were the rubber trim used around the metal housing that I wish K&N would have given more of and the fact that removing the intake plenum removes the support for the heater lines which could rub a hole in a plug wire if not resupported. It would be nice if K&N had a note about this in the instructions but I managed a 2 minute fix, no big deal. I installed the intake with about 40k miles on the truck. There is a noticable volume difference (good difference) in the truck when you get on the throttle, but nothing I would call loud, especially in the land of big diesels. Around town (30 MPH speed limits) or even driving down the highway, there really isn't a noticeable difference in sound. But it really sounds angry when doing 75 MPH across an open field in 4th or 5th. Also, when getting on the throttle hard, you can feel feedback in the pedal but not concerning. As far as actual throttle response I do not notice a big difference unless using the select shift fully. There is definitely a power boost around 3500-4500 RPM. My experiences may differ because I live at 4800' elevation. I'm sure at sea level there is a much bigger change. I have about 10k miles with the intake now, around 50k total mileage. No issues and still very happy with the purchase. I'm also seeing about 1 MPG gain in fuel economy (14 MPG to 15 MPG) which if you have a Raptor you shouldn't really care about anyways. We didn't get these things because we're concerned about the environment, right? Overall, very happy with the K&N intake and would recommend for anyone.
