Funny, Wix is supposed to be one of the best out there in terms of filter construction. I recall this being debated quite heavily on a Chevy / GMC truck forum a few years ago (a "what's the best filter" discussion got very involved and technical). I'll see if I can dig up some info but IIRC the filters were extremely well made and would stop the finest (or some of the finest) particulate contaminants.

Maybe they cheaper out like everyone else now - dunno. I'm surprised to hear of Wix being problematic though. I used them religiously for years. I think the same or similar discussion came up in the 944 forum a while back too.
