I saw a K&N oil filter at Wally world and wondered what the filtering efficiency is? I looked at the cartridge version for the Pentastar and the construction looks to be of good quality, as does the media. Does anyone know what the efficiency rating is for these? I've looked at K&N's website and can't find any information on that.
It's not a filter I'd necessarily consider. I can get a Fram Ultra for a little less and I've got a gut feeling that a Fram Extraguard would actually filter better.
