Does the E legitimately replace the B?eBay Link:

I've bought a few from this seller and they're authentic.
B is Japan, E is Mexico.Does the E legitimately replace the B?
Dude, no, wrong filter.Well I placed an order for 3 15208 9e01a
A mod in this forum even suggested it in another thread. Saying it's a GTR filter that's just larger capacity?Dude, no, wrong filter.
Nissan 15208-65F1B or 15208-65F1E
These two, only these two, period.
Dammit. 15 psi. That's what I get for not checking again. Why would a GTR have a lower bypass pressure?Dude, no, wrong filter.

Different engine, different requirements.Dammit. 15 psi. That's what I get for not checking again. Why would a GTR have a lower bypass pressure?
I read all those threads in the beginning and I think that's where I got it in my head about the 9e01a. I even have a screenshot saved so I could reference it and get the right filter. I think a lot of people like me also assume that the GTR being a TT Nissan motor will have the same specs as the Z, just a bigger canister which would be a good thing.The 9E01A is the ‘09-‘20 GT-R filter, which has a longer can than the Z’s 65F1B/E, and it fits, but I‘m pretty sure it has a lower bypass pressure than the Z’s needs.
Another thing, and I don’t know where the confusion started, but when I first joined here, a couple months before I got my Z, and possibly until shortly after I got it, Z1‘s RZ34 oil change kit came with the 65F0E, which is the 370Z filter, and has a lower bypass pressure like the 9E01A. It’s possible that was just the pics, but I’m pretty sure people here bought that kit and got the 65F0E.
Neither the 9E01A nor the 65F0E will destroy your engine, but they’ll both open up and stop filtering the oil sooner than a 65F1B/E. And from what I understand, fine particulate buildup is what causes the oil pump control solenoid to fail.
The bypass pressure rating isn't for absolute engine oil pressure, it's pressure differential across the filter media. Basically, if your oil filter clogs it will cause the differential pressure, or spread, to spike. This is when the bypass valve opens to ensure even with a clogged oil filter the engine remains lubricated.I read all those threads in the beginning and I think that's where I got it in my head about the 9e01a.

The bypass pressure is a huge rabbit hole when you start to factor in regional weather temps and if you're running a different weight oil than the spec'd 0/20. The bypass pressure can also change depending on the type of filter media.
At 24 psi bypass...are our cars in bypass mode at startup? If so, the Mobil filter I have in the car right now won't matter, except in high rpm situations. That would buy me time to swap the filter out with the correct one.
Oh I know. The more I think about it, the more it seems to me that the bypass pressure is less an issue than I originally thought.The bypass pressure rating isn't for absolute engine oil pressure, it's pressure differential across the filter media.
