Take the filters back to the dealer. Ideally, bring a used one with a leak too. They are pressure tested at the factory, but no QC process is perfect, and sometimes these things show up after some heat cycling. If the dealers is any good, they should swap them out for you.

It's not uncommon for high volume products like this to have recalls, but you won't know about them unless you search the manufacturer's website. Every manufacturer has had them. You just can't make a million commodity items perfectly every time.

The Mazda filter (Tokyo Roki) compared to the current Subaru filter (Fram) has better filter elements and is actually of a larger capacity, both of which are advantageous.
Better how? What's the media type? filtration specs? Flow capacity? Bypass pressure rating? If you KNOW any of this, please share. Up until now no one has produced this knowledge, (or at least not that I've seen) and have only stated that it's better for completely subjective reasons. If you're going to sell it as a product that can improve longevity, you really need something to back that up. Alternatively, maybe a compiled list of premature engine failures due to the OEM filter failing/defects and compare that to some other brands to establish a 'normal' defect rate.

The Suby blue filters are no longer produced by Fram. Plus Fram has been bought/sold a few times over the years with accompanying changes to management to 'better fit market demands', or 'improve' this and that. None of this matters as much as you think, because the build specs are all provided by Subaru, so no matter who makes it, they all have the same performance specs. Now if the OEM supplier has a QC issues, that absolutely does throw a wrench in the works, and as I said earlier, ALL OEMs at one point or another has issues. Especially with a commodity item like an oil filter.

This thread has gone OT, but for those that MUST have bigger, and believe the people who designed the engine and oil filter specs might have known what they were doing (otherwise, why do you even drive a Subaru), then just get an Ascent Oil Filter (cough cough, we sell both on our site if you want the part No). Same filtration, bypass, burst rating, etc. and about double the filtration media.

What results? Bench testing? Please post.

That vid has zero data except for subjective observations, and the Suby black filters are what come from the factory on EJs and considered a break-in filter. There is about half as much media in them. I would never run them a full OCI, especially if you're going to push to the factory recommended OCI. Shouldn't matter to most here, since enthusiasts often change oil long before the recommended interval, but a safe assumption to go by is the loss area, the larger allowable particle size (poorer filtration), or, lower media area will give a higher pressure drop across the media.
