Tom Angotti, North Carolina
Awsome filter! I have a 2011 Silverado with the 6 cyl engine. This filter really improved my throttle response and low end power. OEM replacement filter costs almost half of the cost with no gains. Well worth the money!!!

Purchased for my friend's truck. He loves it and it fit right in the OEM air box!!!!! Worked great!!!!!

Exactly as described and works as such. Could swear the engine noise was audibly different.

Excellent product. Have noticed immediate improvement in performance and a nice growl while accelerating my V8. Wish I had not waited so long to make the upgrade.
