Filter fits exactly as stated. Do notice an increase in power. Not many miles on it yet. THANKS to K&N for a great product.

I have used K&N filters in all of my vehicles for years and I think they are the best filters to use.

5 is my rating. I installed the filter on my truck and immediately noticed the difference. Good stuff.

Five Stars for sure. Love the filter and the increased HP and mileage. Would really love an intake kit for the Chevy 6.0l in the 2013 Suburban
