I have installed K&N filters in all of my vehicles since 1990. Great product.

Fits perfect on 2013 Chevy Silverado LT. Notice the filter is smaller in depth than the stock. Notice a little improvement on throttle response but I already have a 3 muffler exhaust that made tremendous power and pickup, but it sounds like more air flow when floored. I was getting 17.5 miles to the gallon but I reset it and now I am getting almost 19. Hard to believe but it definitely makes a difference. If you don't have a muffler exhaust then this would be the cheapest and most efficient way of increasing power and mileage. Thank you. Very satisfied.

Excellent product! I could feel the difference right away as it allows more air through the filter. When I hit the gas it gets up and goes.

Bought a K&N filter for my 2011 GMC Sierra. I am very happy with the extra horsepower and savings from not having to buy an air filter every 3500 miles.
