Oil filter OEM BMW or OEM Subaru

Not only is it fine, it’s widely considered the best option for the WRX. I have had multiple cars and always did my own oil changes. On my first oil change on the WRX I used my (at that time) tried and true Mobil 1 high performance oil filter and the seal blew and made a mess. Luckily I caught it before any damage was done. Since then I’ve exclusively used Subaru OEM oil filters and had zero issues.

I use the black OEM filter and Pennzoil Ultra Platinum. The platinum and the Ultra Plat is the same formula now I’m pretty sure. I’d stick to the OEM filter too. It’s what my tuner recommends and I wouldn’t go against what he says unless it’s literally written in the stars

My lovely girl friend has a 2 door BMW 1997 325i. It's a very pretty car with 176k miles on it. We drove it all over and one day it hit me, when was the last time the oil was changed? She thought her parents maintained it, but after some digging the oil hadn't been changed in 1 1/2 years and possibly 30k miles. I pulled the filter out and it was worse than this, and just fyi BMW filters like these do it kinda often from what I have read.

Then engine had 2.5 out of the 7 quarts it is supposed to have. (poured the oil in a 4 quart jug to see). I have absolutely no idea how it lasted so long. It was a ticking time bomb. So after 6 quarts of oil and the seventh being sludge cleaner, the engine has no more ticks and runs very well.
