I use Puralator Boss filters on my EVO now strictly, they’re high quality synthetic media, with everything you want in a quality oil filter
Fram still makes the synthetic media filter that was originally my original go to in all my vehicles called the X2 then they XG you’re mentioning called the Ultra Performance, I believe there are still some hanging around but now they are switching them to an all black filter and are calling them the Fram Titainium.
the higher end frams are hard to find/get on amazon what's the purolator part #? is it the oversized one like on the 3000gt? later oil filters always want to stick the smaller one on the evo.
nice even flow on my oil gauge my last brand would suffocate at 8000 rpm "scurry", but this seems to keep a good pressure just a little decrease. good stuff.
obviously no idea what kind of car and what kind of situation the above pertains to, but definitely a good sign that someone is looking at how it flows in terms of oil pressure. all oil filters should be fully open at that rpm, but sounds like some still flow better than others. not always about the filtration media.

I sell/use Purolator filters. The PBL boss filters are legit! Very heavy in weight. I use one on my cousins 1.5L ford ecoboost Bronco. 7500 miles and the full synthetic oil looked in great shape.
On the EVO, Purolator pushes to a PBL14610 filter instead of the fatter, normal 4459 filter number.
I started using hyundai/kia oil filters, made by MANN. Part no: 26300-35505. Identical to the OEM black filter, but blue.
No, I been using that Hyundai OE filter 26300-35505. Diameter is too small on the 4610 you're right. Alternates I'm crossing now are Baldwin B7243, but still narrower despite the seal surface matching. Should be over 3". Next oil change I'm gonna put the Mitsu filter back on and compare.
how much of the oil pressure in the engine does the oil filter see? most bypass valves are 9-15 psi, I assume that's not 9-15psi of oil pressure, we'd be over that almost all the time.
i'm looking at fram racing oil filters - they have a higher bypass pressure valve (20-25? psi) and freer flowing filtration. Figure if I've got an oil filter that is essentially bypassing all the time, maybe it's better to use an oil filter that will flow more (but protect less) and bypass less.

Bypass pressure is pressure delta (difference) across the filter.
So if it's 10psi to open the bypass, there needs to be 10psi pressure drop across the inlet and the outlet of the oil filter.
This ONLY happens when the filter is full of debris, new oil filters have near zero pressure drop across them.
I tested a few oil filters to get these results.
