Lawrence Myers, United States
I am already noticing an improvement in gas mileage and performance. I like the idea of long-term driving between filter cleanings. This is the third auto that I have bought a K&N filter for.

I had an air filter in my Dodge Ram and I swear I got 2 more miles per gallon of diesel. I will always have one in my car. I love them. THANK YOU -Richard Lloyd

I've always put K&N air filters on all my vehicles. First time buying through K&N's site. Easy to use, quick delivery.

19 mpg with aftermarket air filters - 21 mpg with the K&N!! Cleaning and recharging is a snap and saved me from buying another disposable filter. Impressed enough that my wife's '06 Forester and my '97 Wrangler now have K&N's. I clean all 3 at the same time to save time and no longer buying throw aways saves me money!!
