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.

Super easy to install, perfect fit, and quality second to none. I've been using K&N filters in all my vehicles for several years and they are everything as promised. I will continue to replace my stock filters with K&N products in the future as well. Best product you can buy for the money.
