I just cut one of my Fram Ultra open from my latest shipment a few days ago and it’s still the same high-quality build. Nevertheless, the product itself is still the top choice for my shop.
The Mazda filter has a higher capacity and larger design compared to the OEM Subaru filter. So, it will hang down slightly lower than OEM. The anti-drain back pressure seems to be similar, but I have never verified myself. I ran this filter on my 2005 Impreza WRX STi for a few years.
There's quite a large selection of Fram and Motomaster filters for almost any imaginable make/model.
I’d high recommend doing an oil change with 10w30, putting on a factory oil filter (they’re about $10 at the dealer and come with a crush washer), and seeing how it behaves then. I recommend factory filters because for some very odd reason, I had less (or no) lifter tick when I used factory filters vs. aftermarket.
I got a few Fram Endurance filters based on what people at Bob’s say. The filter uses full syn media rated for 25000 mi (whatever) vs. cellulose, and has a good efficiency in catching finer 20 micron particulates.
Fwiw, a lot of bmw guys have problems with certain filters that are slightly too long for the housing and compress/bow out. I think fram was the culprit on the n54.
Subaru filters are made by Fram/Honeywell, Supertech filters are made by Champion.
Fram sucks, I have always been a purolator fan or OE
Fram is garbage
Some mechanics refuse to use Fram filters for good reason, they are the lowest quality filter you can possibly use, he doesn't want to be the last one to touch it if something happens.
