The Mishimoto low‑temperature racing thermostat is designed for the 2004–2010 Mazda RX‑8 and opens at a lower temperature (169°F) compared with many standard thermostats, allowing coolant to flow earlier for improved cooling efficiency. Intended to reduce high engine temperatures during track use, the thermostat fits the RX‑8 and is backed by Mishimoto's lifetime warranty.
