Delivery was on time and as usual, the product is top of the line and very affective. Cold air system is next.

This product is superb / excellent. My 2016 Acura RDX AWD became more responsive and added few more horsepower. My engine can breathe more freely. And you can really feel the difference. I highly recommend K&N Air Intake Filters to everyone. Try it and you will never ever say goodbye..

I've used K&N Air Filters before and will use them again in the future. They work well and actually save money over the life of the vehicle!

This is the 2nd K&N air filter for me on Acuras. Although I know their reputation is a slight bit of added horse power & practically lifetime of the vehicle. HP is a great asset, but I'm more interested in a little help at the mileage side. Also, when it came time to clean & oil it, that was a piece of cake. Thank You All at K&N!

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.
