Subaru Oil Filter Fitment Choices - any Subaru oil filter experts out there ?

[zeroptzero]

My brand new 2024 Subaru BRZ comes with a black Tokyo Roki oil filter, made in Japan. This filter is a bit shorter than the previous generation filter - the old motor was a 2L variant, my 24 has the 2.4 L motor. I don't know why the old motor had a larger filter - taller. I see dealers in the US are substituting some blue filters and even aftermarket filters as there may be a shortage of filters for some odd reason. I also see some suggestions of going back to the first generation filter (taller) and that it may supersede the new filter. I've ordered a supply of the new (shorter) Tokyo Roki filter from Japan to hold me over for a bit.

I cut open the factory fill oil filter (black Tokyo Roki) and it looked great, the construction of it is better than the fram produced filters in North America. I'm hesitant to go to the first generation filter as there must be oil pressure differences, and the new 2.4L motor has some oil pressure issues under heavy load and cornering (not something likely to affect me). I don't want the blue filters used on my car even if they do meet some kind of minimum spec.

My original filter is 15208AA170 , the first generation filter was 15208AA130. I know years back Honda changed filter sizes and tried to get one filter to cover many vehicles and there was some oil pressure differences between the original filter sizes, but they continued with allowing smaller filters to replace larger filters etc.

Has anyone run into this situation with Subaru filters lately ?

Wix has the WL10078
There's this weird name Amazon filter
Partsgeek has a Full filter listed, but I don't know the original Full part number (Worldpac replaces it with their own, but the original part number will appear on the box)

You could go to Toyota parts counter and see what they sell for a 2024 Toyota 86. Seems like it would be good to go.

Toyota has been reverting back to the first generation filters too.

Thanks, I am wanting to stay with an OEM part , Subaru or Toyota , you are right that is a weird filter, lol.

There was a shortage a couple of years ago, didn't know this is happening again. Wonder if this is a Gen II BRZ/86 only or across their lineup.

Here we go again!

This has been asked and answered ad nauseam for 15+ years. There is absolutely nothing wrong with the Subaru blue OEM oil filter, if there is show me a single failure reported. If you like the Tokyo Roki filter just buy some of those but please don't complain about the higher cost. Just because they look nicer in your opinion doesn't equate to anything in terms of better quality or performance. If you want OEM those are your choices, forgive me if I sound like a jerk but this is and never-ending topic of conversation and it seems like no matter how many times someone asks about it no obvious answer suffices.

Unless things have changed in the last year, the blue filters aren't even a thing anymore. They have been replaced by Indonesian made Tokyo Rokis. The number for the longer ones is 15208AA21A. I am not sure the shorter version number.

If you need a reliable source for 15208AA170.

This video shows a number of points pro and con. The Tokyo Roki has more media than the larger Fram.



There is also a Baxter adapter that keeps the oil up top, which the forum has discussed before. Don’t know if you hear some start up rattle on cold starts.

Can't go by media area when comparing two totally different media types. The Titanium doesn't need more area to have high efficiency and good dP vs flow performance - pointed out many times over the years. Just look at all the "holes" in the Roki media when shown under 100x magnification.

Mr. Subaru has been testing Subaru filters for years. We use Wix XP series on our H6’s.

^^^ I like the Indonesian filter design better with the coil spring.

There is more media. And I purposely avoided the cons. It isn’t my car.

So? ... more media doesn't mean anything unless it's the same exact media. It's another on-going misconception.

It is a simple statement. More is more regardless of anything else. Way more, surprising how much more media it has. Since he ordered some from Japan already don’t want to go down negativity alley. It’s his decision not mine.
Light spots through media is in its infancy, maybe later there will be more tests covering more media so it can be said it isn’t a fluke result. 100x is a very small area looked at.
The other video I didn’t see much testing.

Just clarifying if someone automatically thinks more area or more pleats means it's always better ... that isn't always true when comparing different media.

The media should be pretty homologous over the whole area, so what WCW shows in his 100x shots is going to look the same regardless of where on the media it's looked at. Prove it to yourself with your microscope.

It’s to me more someone shouldn’t assume a bigger can is better, that it has more media. More of the same as a bigger can.
Media should be the same all over assumes manufacturing is perfect.
Different topic. When wavy pleats are shown it seems to me that it is stretched media, which is no longer the same structure as before.

Sure it's more, but doesn't automatically mean it's better if comparing two totally different medias. People thinking more media is always better don't quite get the whole aspect of how different media performs.

Not talking about 100x shots of used wavy media. Talking about 100x shots of new media like WCW shows. Checkout how homogeneous the new media is yourself on some new media, you have a microscope setup from what you've mentioned before.
