The supposed benefit of the TRD Oil Filter
is that it allows more oil to flow
through it and has better filtration than regular oil filters. Kinda like how their Performance air filters work, except with oil instead of air.
It would be difficult for the average consumer to tell if that's really true or not, my guess is that a big company like Toyota's TRD
division, that banks on
their good name and reputation is not going to risk the liability of flat out
lying about a products capabilities.
But who knows, such things are not without precedent. Leap of consumer faith I guess
