K&N E-0665 Air Filter Product Reviews

Appears to improve both performance and exhaust sound. Very satisfied.

I checked at auto parts stores locally and it was going to take a week to get it. It is for a 2014 Corvette and I ordered from K&N directly and got it in 4 days at a cheaper price. I have used K&N on all previous Corvettes. I gained 1 to 2 mpg and gained some horsepower. It is easy to install and takes about 20 minutes.

Nice and simple to order and check out. I received my K&N air filter in just a few days and it arrived in perfect condition, and intalled it that weekend. I'm looking forward to purchase other K&N products in the future. Great Product

Easy to install and noticeable improvement in sound and acceleration. I've installed K&N filters in all three of my Corvettes and in my 1996 Porsche Carrera 4S.

I have used K&N filters in all my performance vehicles from a Z28 Camaro, Trailblazer SS, C6 Vette, and my last vehicle a C7 Vette. I am very pleased with the performance I get from this fantastic product. I would recommend it highly to anybody looking to improve the performance of their vehicle for more horse power. Get It!
