Top Amazon Reviews


  • Appears as good as OE
Appeared nearly identical to the original thermostat. Fit in as you'd expect and is operating fine. I trust Aisin products to be truly equal to OE Subaru parts and they consistently show that. Was used on a 2018 Subaru Outback 2.5L.

  • Perfect OEM replacement
Perfect OEM fit for my 2015 Crosstrek. I've had issues with the Motorad thermostats so I went with OEM
