i wanna get a greddy or a TRD oil filler cap for my is300.... the is300 doesnt have a threaded filler cap so i was wondering if anybody had put on an aftermarket filler cap and what part number it was... ive tried some of the " latch " style caps but none fit... thanx

I had a chrome breather style cap and the fuxx at the dealership told me i would lose power at 80 mph?

Since the engine (2JZ-GE) is the same as the Supra's, couldn't you just use any aftermarket ones that are made for it. Don't take my word for it, it's just a guess on my part...

Be weary about the aftermarket cap quality. I've seen quite a few that fit, but not perfectly, it left too much "play" between threads (not that it means anything here) so oil vapors and what not leaks out at WOT.

forgive me for sounding stupid, but what do these filler caps and breather caps do? And how much do they go for? thanks!
