A very good product and service.

Quick and easy to order. Filter arrived quickly. Good price. Fit was perfect. I like that I won't need to purchase another filter ever. Early to tell but it feels like my 2018 2500hd is a bit more responsive.

Excellent air filter as always. Noticeable difference in fuel mileage of 1 I 1.2 mile per gallon after installation. I’m a hunting guide on a lot of dusty roads here in New Mexico and I know I can trust my K&N filter to keep my engine protected. Filter is easy to clean when it gets dirty. Well worth the money.

I am disappointed with this filter, I haven't had any increase in fuel mileage at all. To be fair it has only been one tank full so far. Maybe it will help over time.

Highly recommend this filter. Immediate improvement in power and increased my fuel economy by 30. 1100 miles on one tank through the desert.
