🚀 K&N Cold Air Intake Kit for 2001-2004 Ford F150 Lightning & Harley Davidson | High Performance | Increase Horsepower | 50-State Legal | 5.4L V8 | 57-2549 Review

K&N Air Kits are great. My son's truck was sluggish, but now it's amazingly strong. I recommend and will always recommend K&N.

I installed it on a supercharged 2002 Harley Davidson F-150. Big difference much better than factory airbox. It increases the power and the compressor sound that I love

Ordered through Revain. Parts were delivered as promised. Easy to follow instructions. Easy installation. Noticed an immediate increase in throttle response and acceleration. I have two F-150 trucks and both have this upgrade. It also helps with gas mileage.

I installed it on my 2002 Ford Lighting and noticed an increase in performance and I also liked how it makes a little whistling noise meaning it's sucking air but that's the only thing K&N is missing, is a locking screw. They lay down next to the pulleys to keep them from falling off but otherwise very happy with k&n they are always my first choice

AMAZON'S GUIDE WHAT'S THE WRONG FIT, check the fitment at K&N website. I wasn't smart enough to check it on the K&N website so I had to send it back to Amazon and they charged me for shipping and I had to make a lot of noise to get it back as they misunderstood their information, not in me . K&N is still one of the best.

I don't know if the truck is more powerful but it sounds better and my MAF sensor doesn't get as dirty as the old stock filter. Installation requires a little mechanical knowledge and takes about an hour, but the instructions are clear. Anyone who knows the difference between a screwdriver and a socket wrench can install this.

$300 and 2 hours to tear my truck apart and I'm frustrated with how cheap it looks and feels and I can don't even finish installing, let alone on Saturday, and customer service is closed. I'm so sad.
