There are multiple threads on this site and other Subaru enthusiast sites about the new Suby blue filter made by Honeywell (a.k.a Fram) and the different arguments/discussions on the importance of the by-pass valve in the unique high PSID (23) of the Subaru boxer engine. In Canada, isn't the dealer part made by (or named) 5 Star? I've never seen a comparison twixt it and a US blue one (which is made by Honeywell of Canada), so I can't say if they are the same or not. The only aftermarket filter, that I know of, that meets the 23 PSID by-pass valve spec is the Purolator 14460 (L or PL). Though millions of miles have been put on any number of aftermarket filters that don't meet that spec and engines aren't blowing up, so I don't know how important that might be. What model/engine are we discussing?
