Quality at it’s finest
I swapped my stock filter with this K&N replacement and immediately noticed smoother acceleration and a little extra power. Install took less than 5 minutes—it literally dropped right in. The build quality feels solid, and I love that it’s washable and reusable instead of constantly buying disposables. Knowing I won’t have to touch it again for years makes it even better. Great performance upgrade and well worth the price!

Don't believe the scare tactics
Online videos swear that these will ruin your engine. I have used these from the very beginning, since my trucks were new... I now have well over 250k+ miles on my trucks without engine problems or failures. These are high quality, durable, made to fit and seal.

K&N Air Filter challenge. Improve your vehicle’s performance by adding one.
Got this for my Daughters rig. In my humble opinion these are the best air filters on the planet. I put them in all my vehicles. These will improve your HP, MPG. They are easy to install and clean. Improves air flow for improved performance. Excellent product, if your car doesn’t have a K&N air filter, Get one!

Worth the money
Exceeded expectations! Perfect fit and easy install. Averaged roughly 18mpg on a recent road trip for the first time ever. I attribute that mostly to the KN filter. Not much difference in power but thats ok, I drive a Chevy and don't need it 😉

I'm a believer.
I've heard of K and N for a long time. It was always out of my budget for an air filter. But, for once I thought I'd give it a try. The original filter is 2" thick. K and N is 1". After one test drive I could feel the difference. It felt that the engine could breath and took a big gulp of air when I stepped on it. I don't know if it'll get better mpg. But, I'm anxious to check upon my next fill up. The filter is installed in a small Chevy V8...4.8L
