I thought that somebody may find my observation useful. A couple of day ago I replaced an OEM Subaru filter with a Fram Ultra XG9688. And noticed one thing. The oil light goes off quicker after a cold start. I don't know how to explain this. Maybe the bypass valve opens a bit earlier. Or the flow through the filter element is better. Or may be some other factors which I cannot identify. But the fact is the fact. ADBV valves are good on both filters. And this was not my first OEM filter. Previous OEM filters worked the same - light did go off with some delay. So far I am happy with the Fram.

Did you switch to a different oil, too?
No, I did not change oil.

I think all my cars' oil light went off very quick on cold start, I never paid attention to it since I never had the light stayed on more than a second, more likely the instant the engine started the light went off.

Subaru does spec a higher bypass pressure setting, and most of the aftermarket filters will be much lower. Only Wix makes a filter with the correct bypass spec; I believe the part number is 57055.
Hmm first time ive heard that one. BUT! My car ALWAYS had a startup rattle from MILE 1 new and i tried every filter brand out there with no change whatsoever. OEM filters made no difference either. Then I bought a FRAM ULTRA because it was new and I wanted to "try it" to see if it helped.
Since I've been using fram ultra filters I have not had any startup rattle on that car at all. Its been about 30,000 miles since i started using them.
I have heard multiple times now that Ultras have better flow. Im a believer in that for sure.

What data is available to confirm that the Subaru Bypass pressure requirement is bad? WIX filter for the Subaru engines meets the Subaru factory engineers requirement. Ed

Horse doodoo?
I call your post internet hogwash if that is the best you can come up with.
It is a Fact mind you.. NOT an opinion. That all oem subaru filters have a high(er) speced bypass psi. usually around 24psi vs 12psi for most aftermarket.
There is no doodoo in that statement.
Now the whole Why it is higher and if its important is another topic.

What I really don't understand is why Fram makes 2 almost identical filters: XG3593A and XG9688? What makes the XG9688 suitable for Subarus? And the XG3593A not suitable? The 4 mm difference in height? Isn't it strange? Maybe the bypass valve on the 9688 meets Subaru's specifications? I could not find this info anywhere on the Internet.
XG3593A and XG9688 have different threads.

The thread looks the same to me. The base plate looks the same too. Only the height is slightly different. With such a small difference in size it is not worth it even to make different stamping equipment. There must be a substantial reason to sell 2 almost identical (size wise) products.

Yes, they are after looking again - my bad.
They basically look the same, just slightly different dimensions but really close enough to interchange them. Even the bypass valve setting is pretty close to each other.

Ask Motorking why the difference
Strange that nobody even discussed these 2 filters on the Internet. Looks like I am the first who wants to know the difference.

Actually, Fram (which also makes the OEM filter) does have a Subaru-specific model with the proper bypass - the PH9715.

Been there done that. Posted the data on here many times why its a non issue. The engineering data from Motorking for Fram Ultra has been posted many times specifically to answer why there is no reason for the high bypass pressure. Bypass pressure is media specific. There is no bypass pressure spec. Fram makes them both and say there is no issue to run the Ultra in a Subie.
But let's rehash this again. I failed to find the bypass spec in my owners manual. Why it needs to be discussed every month I don't know.

The engineering data has been posted on here many times explaining why it is a non issue including direct statement from Fram who makes both the OEM Subie filter and the Ultra. They have full access to all the performance details and yet the internet engineers who don't have a clue continue to post about this so called bypass pressure spec.
