Mishimoto Low-Temperature Racing Thermostat with Housing MMTS-TUN-07 for Select Lexus and Toyota 2007-2025 (5.7L)

Fits select 2007-2025 Toyota and Lexus models including Tundra, Sequoia, Land Cruiser, GX460, and LX570 (5.7L).

The Mishimoto Low-Temperature Racing Thermostat is a precision cooling upgrade designed to replace your factory unit and housing. By opening at 160°F (71°C) instead of the standard 180°F (82°C) OEM temperature, this thermostat allows coolant to circulate through the engine earlier. This proactive cooling is essential for vehicles operating in high-ambient temperatures, heavy towing applications, or engines modified for increased power output.

This kit includes a stock-style housing to ensure a proper seal and a straightforward, direct-fit installation into the factory mounting location. This assembly eliminates the need for separate housing gaskets or complex swaps. Like all Mishimoto performance parts, this thermostat is backed by a Lifetime Warranty for long-term reliability.
