Great experience working with your company. It was easy to find what I needed and order on your website. The product shipped quickly and arrived on time. We purchased an air filter for our Acura RDX and our Subaru Outback. The filter fit perfectly and my Acura RDX has never run better. I loved your Stop label that I can put on the filter box. Thanks so much.

When holding this filter you can tell its a much better quality product then Hondas cheap stock filter. Putting this filter in was headache free and the fit was very good.

Installed this filter in a 2016 Acura RDX.  Hard to notice if power has improved, even minimally. Have noticed slight decrease in MPG. I do appreciate knowing this should be my last air filter purchase needed for the life of the vehicle. Not sure if it makes sense for K&N to engineer an air induction option to increase power since Acura did a decent job with that already. But if they do, I could be a potential buyer.
