I drove vehicles for years before they even had oil filters ....... yep, sure did ...... (spit).

OEM Tokyo Roki (Subaru 15208AA130)


Don't know what the new style OEM ones are like internally so I won't switch. My only other choices if I can't get those are Purelator PureOne or Wix

Mostly oem. One thing I've noticed though, and I'm not sure it's been mentioned, the Toyota and Subaru filters are different.

Why tho? what about that particular oem filter makes you want to use it? Materials? Pressure relief setting? because JDM?

From what I understand the Toyota filters were just the updated subaru design. the original subaru filters are no longer available. but again, no one can tell me why one is better than the other

When people have cut them open the fins on the Tokyo Roki were much tighter compared to others and appeared to have more media to filter particles. PureOne and Wix were close. Fram, cheap Purelator, etc had less fins so less media to filter, cheap cardboard endcaps, etc.

That just means they clog up faster, rob more oil pressure to the rest of the system, and trigger their bypass sooner.

used K&N but always go back to OEM subaru. Cant beat OEM quality. most aftermarket just charge more for the pretty colour of the filter.

Wouldnt more fines = more surface area meaning they actually can take more, not less before clogging?

I figured particals are so small its not like something large will clog something up in between fins

I remember someone cut open a bunch of oil filters few years back & posted pics of the internals. The black OEM filter definitely looked better quality than the [cheaper] blue OEM version.

Can't remember much about the other ones.. except that FRAM makes crap filters. Even on their best filters (Ultra Synthetic) they still use the same crappy base plates & bypass valve as their regular cheap filters. I think someone on this forum once stripped the threading where you screw in the oil filter because the threading on the Fram filter was wrong too.

OEM generally because that’s what was designed for the car.
TRD “just because” and I like the red...

OEM on the BRZ, but I've also used M1 and Bosch filters on my other vehicles/motorcycles as well since they are usually pretty highly rated. Just stay away from Fram.

With filters, the more higher quality media the better, up until the point where it's excessively robbing power. This can be achieved through more, deeper pleats to increase surface area, (filters a higher volume with a potentially denser/tighter media.)

The OEM Subaru Black Tokyo Roki filters are excellent quality and cheap to buy 6 at a time on Amazon so that's what I roll with. On my EJ powered cars, I run OEM Mazda RX8 filters, which are also made by Tokyo Roki and have all of the original STi specifications of the larger, higher quality filter.

I've had the lower quality filters have media blowouts causing weird oil pressure events on built motor cars with high flow pumps. This has never occurred on the same cars with the Tokyo Roki manufactured filters. (This occured with a current EJ Subaru blue, fram, and lower end Purolator, (not the PureOne filters.)

Edit: I have a huge pipe cutter that I cut open every oil filter I take off a car with to inspect for obscurities. A quick visual for damaged media, a failed bypass valve, excessive glitter on the media etc can tell me the oil or filter isn't doing it's job and a Blackstone test is in order, or the engine is about to go kablooey.
