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.

Great air filter, I had one on my truck & wanted to replace the stock air filter on my wife’s car. I wish I knew that the “STOP” sticker was included with the filter. I wouldn’t have ordered the sticker separately.
