Mishimoto Racing Thermostat 155°F / 68°C for Select Lexus, Scion, and Toyota 1992-2013 (MMTS-SUP-93TL)

Fits select 1992-2013 Lexus, Scion, and Toyota vehicles, including GS300, IS300, SC300, Supra, Tacoma, Yaris, Echo, and Prius.

The Mishimoto MMTS-SUP-93TL Racing Thermostat is engineered to improve cooling efficiency by significantly lowering engine operating temperatures. Unlike standard thermostats that remain closed until the engine reaches high temperatures, this racing-spec unit activates at 155°F (68°C). By allowing coolant to flow through the system earlier, it helps prevent heat soak and maintains more consistent temperatures during high-load driving or in extreme climates.

This thermostat is a direct replacement for the OEM unit, fitting into the factory housing without modification. It is an essential upgrade for tuned 2JZ-GE, 2JZ-GTE, and 2TR-FE engines, as well as high-efficiency 1NZ-FE applications where heat management is critical for performance and longevity.

• Activation Temperature: 155°F (68°C)
