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!

Just do it!
Ordered one for my 13 5.3 Silverado after disabling AFM. Couldn't be an easier install! I noticed a better sound and improved pedal performance immediately with a slight increase in MPG. Amazon found me one for a discounted price as well! Thanks K&N 👍 Thanks Amazon 👍

Excellent!
If you don’t wanna keep replacing filters, get this quality and rubber seals create tight fit.

I really want to say this is an excellent product. I have just installed this in my Thar 2022 model, and it has really transformed my car. The average has increased and the power delivery has increase. A must upgrade for every Thar owner.
