Mishimoto racing thermostat for the Nissan 370Z / 350Z and Infiniti G35 / G37 (VQ-series engines). It opens at a lower temperature than stock, letting coolant flow through the engine sooner to reduce and maintain cooler temperatures — ideal for modified and turbocharged applications. Direct-fit replacement, backed by the Mishimoto Lifetime Warranty.
