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.

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

Another Amazon Warehouse deal that was excellent. Outside of box had some dents but the filter was untouched and even the sticker was still there. This was the trucks first and only air filter replacement. Well that is until I can pull the trigger on a cold air induction unit. The screws in the air box were quite tight and the one by the rad is in an awkward spot. Once the screw were out the top cover needed some twisting to get past the fender support bar. Once past the bar the cover clears the way for the filter to come out. Good time to clean out any debris that has gathered in the air box. This new filter is half the thickness of the paper one but filters better and allows more airflow to the intake. Reinstallation was straight forward. Just make sure that there is a message on the outside of the breather box saying there is a K&N filter inside or your next trip to the garage might end you back with a paper filter.
