To tie this in to what I'm thinking..The Hyundai/Kia OEM reviews are great but why? I read it gets rid of the anti-drainback tick. Really? Is that really the problem, or is it simply a low efficiency Asian filter (like Toyota and Honda) designed for an underpowered/weak oil pump? Ahhh Now we getting somewhere on this suspicion I have ..

"Some vehicles may experience an engine knock noise with the use of an aftermarket oil filter.

My translation:
"The tiny arse oil pump is not strong enough to push oil through the tiny holes of a high efficiency filter. You gotta use our low efficiency better flowing filter. Dirty oil, but she won't tick".
