Is there anyone on here who is currently useing a TRD thermostate on their 3sfe or 5sfe? If so how well does it work over stock and is there a noticable difference in how cool the engine is over stock.

Im considering getting one for my car but I don't know the part number for the 3sfe and I havent talked to anyone who has this part.

Can anyone help me out?

3sgte fits the 5sfe so im guessing it should fit your 3sfe, i bought one back in 2003 but when i recieved it i just got the trd box, so i got jipped and never knew if it helped
