The OEM filter sucks, if you like cardboard end caps fragile filter media, and a antidrain back valve that hardly works go ahead.
Have you ever done a UOA? If not then you know jack of how your oil is working.
I rather just buy a Pureone if I had to pay or get a K&N/M1, Bosch D+ when they are on sale
