i think the fact that most all the toyota engines use the same oil filter is cool, V6's, I4's, and I6's. i have a 3.0 v6 4runner, my dad has a 22re 4runner, and i just got a 22r truck. they all use the same filter, kinda cool, compared to most companies at least. we go to the dealer and buy a few at the time, they are cheaper too that way, at some dealers.
