As noted topic filter is cartridge not spin on/canister type. OT That said, the inside of Denso FTF spin on not the same as Thia Toyota Denso oem. Former use metal endcaps and latter are no endcap type with very similar element to cartridge shown. And as confirmed by member Hootbro
here the new Denso FTF with China coo use a black nitrile adbv, as noted older FTF used red silicone.
Current Denso website info for spin on OF, not accurate for both element type and adbv composition. Another member reached same adbv conclusion as Hootbro with comparison of old FTF to new as
posted here. So, the "preponderance of best current evidence" says the newer FTF spin on use nitrile adbv.
To topic, can't see or think of any reason why topic cartridge wouldn't be fine for 10k mi. fci.
You keep saying this, almost word for word. Have you actually reached out to Denso?
I have and they've confirmed that the FTF filters are still built with Silicone ADBV.
