TOYOTA OIL FILTER CUT OPEN

Afaik, that's correct and why I stated I believe if the test is done, it will follow the simplest answer, it's nitrile. Same as the Denso FTF. Put another way, I'd be shocked if it's other than nitrile. I don't recall a claim here that the topic Toyota Thia Denso adbv being other than nitrile.
At 3k miles in one year, I'd expect most any filter to 'look' good.
Yeah, I said I highly doubt it's black silicone, but a simple test would verify instead of speculations. Still waiting for anyone to find a black silicone ADBV in any oil filter regardless of brand or model.
Here's a link to DENSO's website that says the (black) ADBV is silicone. Is it really?
https://densoautoparts.com/filters-oil-filters.aspx
Note that the red area is just showing all the cut-away surfaces ... the red is not indicating that the ADBV is red. I have never seen a red or orange ADBV on a DENSO oil filter branded as "Toyota".
Here an email from a Toyota dealership that says it's silicone, but consider the source on that one.

^^^^Don't want to belabor the point but that pic (post numerous times before) and info is from the Denso ""First Time Fit" OFs now made in China, filter site. The black can at top of that site is the newer FTF made in China black can. In addition to showing the now proven wrong info about silicone adbv, it also shows incorrect pic of the filter element. 'FTF' OF always used metal endcaps even before moving production to China. The OP of the linked thread also confuses the Toyota Thia Denso (no endcap), with the info of the Denso FTF made China black can. FTF before moving to China production had a blue can, and orange silicone adbv. I've long said, they just left the silicone adbv info up on the site. In summary Denso FTF and Toyota Denso two different filters, different construction, however 'I say' same nitrile adbv.
Only one way to really find out ... do a "burn test". Not hard to do. Nobody has actually done a burn test on a "Toyota" branded DENSO oil filter that I can recall. We can all say it's most likely nitrile, but without verification it's still just a speculation, be it a good one or not.

I'd say they are plenty good enough. Whether they have all of the features you're looking for or not, they meet Toyota's quality standards and therefore probably will not fail. I've been using them at virtually every oil change on my Tacoma since I bought it new in 2002. 20 years and over a quarter of a million miles later and we're all good. If you buy them online by the case you can usually get them for around $4. Or you could the last time I bought a case.
The bulk prices make these really well priced. The construction is immaculate.
Absolutely. I especially like how the end is sealed with plastic and the o-ring is pre-lubricated.
You asked, it seems WCW heard your request.* As noted, count me as very surprised and incorrect 'on this one'. Afaik, 'the first ever "black silicone" adbv seen/confirmed. Doesn't seem as dramatic a visual as the China Denso FTF (nitrile) compared to Puro Boss silicone, however white smoke and odor commentary confirms. In this case, result doesn't follow Occam's razor principle, but confirms the academic statement, there 'can be' black silicone.
Otoh, despite information provided to the contrary, the Fram and China made Denso FTF black adbvs confirmed/proven to be nitrile. Info on Fleetguard OFs says black adbv also nitrile.
As for topic filter tested efficiency and using the OEM, my attitude always, folks should use the OF of their choice. That said, if one is ok using an OEM that tested ~50%@20um, would seem logical also be fine using an OF like the Wix XP/Napa Plat with a very similar rating. Mentioned because the latter are regularly flogged on this subforum for their rating. ¯\_(ツ)_/¯
Burn test starts 9:22
Those filters are extremely well made. Smooth surfaces, smooth machining. No burrs like we see on some other brands. Nice even and clean threads on the baseplate. The ADBV being silicone is a nice surprise though I would be happy with any material as long as it works well. Nice even pleats. The cellophane wrap with prelubed gasket finishes off a great filter.
Was that melted silicone he dabbed onto that plate?

Yes ... when silicone burns, it gives off white smoke and essentially turns into a whitish-gray powder. Looks exactly the same as the orange silicone ADBV I burned (link in post #6).
Okay thanks. I thought it was melted product. That would have been interesting at supper time.
Update. The adbv in the video is "Green" not black according to WCW. "I" missed his comment about adbv color at 3:38, he says "green" there but then assumes it's nitrile and why tested. I just assumed it was black as I can't recall seeing a dark green adbv on the Toyota Thai Denso. So, the "black silicone" adbv remains still only imaginary.
My apologies for incorrect adbv color ID in the OP.
But, happy not proven wrong on" black silicone" adbv. 
Occam's still in play for black adbvs.

Could also be that it looks "black" in everyday lighting, but looks like a blackish green color under strong lighting. The kind of artificial light may also make the color look a bit different than in natural light.
That's how a silicone ADBV will burn. Hardly any flame, and whitish-grey ash and white smoke. If it was nitrile the smoke would be like rolling coal as shown in the photos in my burn test thread.
Thanks for doing the test Stude.
PS - That black ADBV definitely looks black (not greenish) in your photos.

So now we know that the black adbv used in Toyota DENSO filters is silicone. Glad I did the test and was able to see god result

I guess occam got this one wrong.
