I don't race, and I don't inspect my oil with an electron microscope, so I can't comment on the quality of this filter in comparison to others. But hey, it installs, it does its job, and my engine hasn't died. Good enough for me!
Great filter with a substantial rubber gasket seal! Will definitely buy again!
I just wanted to add that they sent me a really nice Moto GP and Super Bike calendar free with my order which was not expected but is greatly appreciated! Thank you MotoSport!
