The Mishimoto racing thermostat for Subaru BRZ, Toyota GT86 and GR86 applications is a lower-opening thermostat that promotes earlier coolant flow for cooler engine temperatures in stock or modified FA20 engines. Offered as a direct replacement, it opens at a lower temperature than standard thermostats to reduce peak running temperatures and is backed by Mishimoto's lifetime warranty for peace of mind.
