Good info, OEM filtech, K&N and mobil 1 are the only filters I've ever used. I've heard bad things about fram since before I even started driving. Lmao at the mugen filter, mugen makes amazing shit but $36 for an oil filter is just fucking ridiculous. Just picked up some 5w-30 royal purple and a royal purple oil filter. I didn't even know royal purple made oil filters but it looks like it's just as high quality as the other filters listed.
