K&N 77-2579KTK Air Intake Product Reviews

Monday, May 2, 2016 - Part 77-2579KTK
This is the third vehicle I have installed K&N products. An excellent addition to the Raptor experience. Noticeably more powerful acceleration, especially above 3500rpm. An improved engine tone upon startup. Did notice a small tone variance at around the 2,000rpm mark that had a vibration with it when accelerating, but quickly dissipates after pushing through and doesnt return even at cruising around 2000rpm. Can't wait for a 40 degree morning to see how it performs. Had a Corvette with K&N air induction that loved COLD mornings.

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
