Oem filters ONLY never anything else. Also I have been told oem s2000 filters bump up oil pressure on b series engines about 10 psi kendall gt1 is the best oil in my opinion. Whoever said oem is junk is a fucktard.

Info about the s2000 filter came from a friend who is a Honda tech who tried it. Also Honda only makes 2 filters everything and a special one for s2000's.
