Customer Feedback

Excellent. I notice an improvement in acceleration immediately. I am looking forward for K&N coming out with a new line of cold or hot intake for the 2015 Infiniti Q70L 5.6 v8.

Filter was for my Infiniti G35 coupe and was installed with the help of a DIY video.

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.
