 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.

 I put this replacement filter in my new 2014 Acura RDX, gas mileage has improved by 2 to 3 mpg.
This is around town don't do much highway driving. I know it would work well because had one in my 2010 RDX it did same on gas mileage. Keep up the good work your filters are the best thing since apple pie.
