Mishimoto Racing Thermostat 68 Degree Celsius for Select 2014-2026 Subaru (MMTS-WRX-15)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2014-2026 Subaru Ascent, Crosstrek, Forester, Impreza, Legacy, Outback, and WRX models.
The Mishimoto Racing Thermostat is designed to promote greater cooling efficiency for both stock and modified Subaru engines, including the FA20DIT. By opening at a lower temperature than standard factory units, this thermostat allows coolant to flow through the system earlier, effectively reducing and maintaining lower overall engine temperatures during spirited driving or track sessions.
As a direct replacement for the OEM unit, this thermostat is an essential upgrade for owners looking to manage heat soak and protect engine internals. The lower activation threshold ensures your cooling system is working at full capacity before peak temperatures are reached.
- Direct fit for factory thermostat housing
- Lower activation temperature for improved cooling efficiency
- Activation Temperature: 165.2°F (Stock: 190.4°F)
- Manufacturer Part Number: MMTS-WRX-15
- Includes Mishimoto Lifetime Warranty
