Extremely easy to install. 5 minutes from start to finish. Am waiting to find out results from this upgraded air filter. Satisfied so far.
Brent Gray, Farmington, Utah
Great product. I have purchased several of these filters for my other vehicles and find them easy to clean and reuse. These filters cost more upfront, but will save you money (not having to replace them) down the line.

K&N is very professional. When I received a filter, I found there was a dent in it. After emailing the issue to their support, I received a reply within an hour and the promise to ship me a replacement free of charge, which arrived in a few days.
