K&N 57 Series FIPK Air Intake (50-State Legal) Reviews


K&N CAI - thumbs up

Reviewed By Eric S (AUSTIN, TX) Reviewed for a 2004 BMW 3-Series —8/1/2017 10:06 AM

Improved throttle response. Slight but noticeable HP & torque gains. Throatier engine sound. $69.20 promo savings + $25 K&N rebate = a $346 CAI for $251.80. Can't beat that. Seems as good as the aFe CAI I had on my prior E46 M3.

Good purchase

Reviewed By James W (DUKE CENTER, PA) Reviewed for a 2013 Toyota Tacoma —9/21/2017 2:05 PM

Easy install. I took my time, 2.5 hrs! The provided fuel pressure vent hose was 6" too short so I put a connector between them and it works great. I told the rep at K&N about the short hose and he made note of it. It should have been 18". I was told to do normal driving for 100 miles so the computer can learn. It sounds pretty cool when you add pressure to the pedal! I installed it for added horsepower.
