oe , my oe timing belt had 185K on it and was just cracked a bit after seeing what good condition it was in considering the mileage i wouldn't use anything else.
and I bought Toyota. I had previously bought a Gates and it's still there in my spares box. (Is posting that OK? I'm sure a mod will tell me or delete if not).
The gates belt is actually slightly thicker than the OEM belt. When I replaced mine I bought both and compared them, I figured the thicker the better! lol
