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.

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..

Too early to know for sure. I do like the ability to reuse the filter and save money in the long run. Many people don't know how easy it is to replace your own cabin filter. Most dealers charge $80 and up to do a 5 minute job. My neighbor was going to pay $85 to have her's replaced in a Honda CRV. I said...No you are not going to pay that, It's a rip off I had an extra factory filter, and I showed her how to change it....then made her do it.  Simple I'm not sure about the fit of this filter. It didn't seem to go in it's slot as easily and securely as stock filters.  Might be just me.  Not sure.  I've replaced many cabin filters in different makes of cars.
