I've been using K&N filters since the 1970's on everything from my Hondas and KTM dirt bikes to my Ducati's and BMW, to my off road trucks and Corvette's. Have never had a problem in any way shape or form, as the saying goes. I'm sure my new turbo charged SUV will greatly benefit as well.

Excellent performance achieved after replacing my old paper air filter. Now my Peugeot runs more efficiently and I am helping the planet by not polluting it with old used air filters. Thanks for this super product!

I've been using K&N air and oil filters for many years now, cars and motorcycles. The last car I had was a BMW 525i and I consistently calculated a 3-4 mpg (highway) improvement in gas mileage. I recently purchased a 2012 Infiniti M37 and am averaging 2-3 mpg improvement on the highway. I just like the fact I don't have to change the paper filters often and do notice better gas mileage on the highway which makes me feel a little better since I have to use premium grade. When I checked all the auto parts stores they didn't have them or told me they were on backorder. I called K&N directly and they were shipped out quick. Customer service was above average and worked efficiently. And if you ever decide to engineer and sell automobile CABIN FILTERS that have carbon/charcoal layer and are oiled with a light scent, SIGN ME UP! I hate changing the air filters so often. There is a model of the Infiniti that has a feature called Forest Air that people seem to love. Unfortunately, mine doesn't have it. Just sayin. Thanks.
