I know I am keeping my cars for 3 to 4 years and I put about 35k a year and the reusable air filter especially in the dusty southwest is the way to go

With the K&N filter I'm seeing an average increase of 0.5 MPG, and definitely feel the difference on acceleration. It's nice to see fuel lasting longer with today's crazy prices.

I purchased 2 of these, one for my Frontier and one for my wife's Rogue. I haven't had them long enough to see any real change in performance or gas mileage. Paper filters have increased in price over the years so by these lasting longer and being able to clean and reuse them it won't take long to save money.

A worthy upgrade for any performance oriented vehicle. We have a 2011 Frontier 4x4 with a big honkin' V6, a 2012 Juke AWD SL, and a 2014 Juke Nismo RS. The filters are insanely expensive, so if you don't keep the vehicle for at least 80-100,000 miles you will not recoup your purchase price. But in the mean time you enjoy a mild performance gain.
