Bryan Shinholt, Columbia, Maryland
I love the convenience of buying my filters directly from K&N. It saves me money over purchasing at a nearby auto parts store. So, I get a superior product at a great price. This is a no-brainer.

I own a 2004 Honda Accord this filter is way better than original manufacture equipment filters. K&N filters are of good quality they could be used with conventional or synthetic oil it doesn't matter. You get quick fast flowing oil to the upper part of your engine where you really need it. I have come to trust K&N products because of the good quality and well respected reputation in the market.

K&N Oil Filter; Billet
  • Billet Aluminum Housing
  • Washable and Reusable
Christopher, Imperial Beach, California
It fit perfect. There is no oil leak and easy to install.
Ken, Massachusetts
The product fits my 2016 Crosstrek as it is said to. The design of the product itself is excellent. From a stand point of serviceability in regards to Subaru's though, it is extremely difficult to remove the flange from the Subaru's oil filter connection since the sides of the oil filter pan are slightly higher than the flange is thick and there isn't enough clearance between to get a proper grip with either fingers or tools. If you are looking at this product for a Subaru with the current style pan-like oil filter interface on top of the engine, I would not recommend this product. You will grow tired of prying the flange off before too long or you'll end up damaging it in the process.

Easy to install & maintain. They're expensive but if you plan to keep your vehicle for several years it's no more expensive than purchasing quality filters every 3 to 6 months & there's no filter to dispose of each time.
