The air filter is perfect. Gas mileage and horsepower have both gone up. Will definitely buy K&N products again.

Have used these types of filters for years. They have always worked great for me. I recently just purchased and installed this filter in my 6.2 Silverado Redline 2018. I noticed a difference immediately in throttle response. Going on a 2 hour drive this weekend to really test it out. Great product would highly recommend.
