If you hold it 90 degrees horizontal then the adbv won't necessarily mate to the surface.

adbv is piece #4 in this diagram. how it works should be obvious, as is the bad methodology of the test in those videos.

Hello sir, i am not trying to discredit the manufacturer or supplying false information. I am just trying to show my experience with regards to the oil filter and for the members to see the adbv difference between vic and js asakashi. This filter may be defective. If you want i can send you a new js asakashi oil filter coz i still have two pcs in my custody.
