Denso's aftermarket oil filters feature a black-colored ADBV. We usually associate black ADBV's to be nitrile, not silicone. However, the Denso website clearly states their filters feature silicone ADBV's:

I e-mailed Denso and they replied stating that the color of the ADBV does not matter and their filters have silicone ADBV's.
Is there any way to verify the material of the ADBV?
