Mishimoto Racing Thermostat - 2013-2020 BRZ/FR-S/86

"The Mishimoto racing thermostat for the 2013-2016 Subaru BRZ / Scion FR-S will promote greater cooling efficiency in your stock or modified FA20.Once the engine is fully warmed up, the Mishimoto racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures. The Mishimoto BRZ / FR-S racing thermostat is the perfect addition to your street or track car and is a direct replacement for the factory thermostat. As with all our products, this thermostat includes the Mishimoto lifetime warranty." - Mishimoto
