Mishimoto 01-07 Subaru WRX / WRX STi 68 Degree Celcius Racing Thermostat

Replace your stock thermostat with the Mishimoto 68&deg.C Racing Thermostat designed for 2001-2007 Subaru WRX and WRX STi models. This direct-fit upgrade opens at 68&deg.C (154&deg.F) to promote faster coolant circulation and lower operating temperatures during track days or spirited drives. Compatible with a wide range of Subaru Impreza, Forester, Legacy, Outback, Baja, Tribeca, SVX, and Saab 9-2X vehicles equipped with EJ20 and EJ25 engines.

Key Features

  • Low Opening Temperature: Activates at 68&deg.C (154&deg.F) compared to OEM 82-88&deg.C for quicker coolant flow and reduced peak engine temperatures by 10-20&deg.F
  • Brass Housing: Precision-machined brass construction resists corrosion and withstands high-pressure cooling systems in performance applications
  • Direct OEM Replacement: Matches factory dimensions and mounting points for seamless installation without modifications on EJ-series engines
  • Included Gasket: High-quality O-ring gasket ensures leak-free sealing and reliable long-term operation
  • Laser-Etched Logo: Authentic Mishimoto branding with durable markings for easy identification

Product Notes

  • Always cross-reference your engine code (EJ20, EJ25 variants like TY754, TZ1B4) with the application guide for precise fitment
  • Pair with high-performance coolant and Mishimoto radiator hoses for complete cooling upgrade
  • Ships securely in protective packaging to prevent damage

Installation Notes

  • Professional installation recommended.
  • Drain coolant system completely before removal to avoid spills and air pockets
  • Bleed air from cooling system after install and monitor temperature for first few drives
