I just stumbled across this filter (FULL 2-OSB007) at the local WorldPac distributor - Application is my wife's 2022 Forester.
Would you choose this or Napa Gold? I like the fact this one has a P style gasket... OCI is 6k. This is $6 vs $15 for the Napa, although that doesn't really matter, but it is clear this has been made specifically for this application as it even has the Subaru number on it as well. Napa also has the ProSelect for about $6 but I'm not sure if this FULL is a better filter (efficiency) than the PS or not.
Hi OP,
If the Full brand does not offer efficiency ratings and how they're tested, e.g. ISO 4548-12, I'd then lean toward the Tough Guard or a Purolator One. I'm a fellow Subaru owner and am currently using the Purolator One. They're rated for 15,000 miles with 99% efficiency at 20 microns. You could get two 6K OCIs with a 3K safety factor.
