  • Q: requirments?  bry8312 years ago

    does this thermostat require a tune on my 08 sti?
    • 0 of 0 people found the following answer helpful

      A:  A lower degree thermostat means the thermostat will open sooner, but if used in a street car this can result in the vehicle never warming up properly or taking too long, causing it to run rough. In street applications a standard thermostat is recommended but depending on the setup of the vehicle and use this is beneficial. A tune would not be needed.

  • Q: Recommend?  gmacsu958312 years ago

    I have a 2002 WRX with a few bolt ons and plan to build it to be pushing a decent amount of HP. I daily the car now and have a Front Mount Intercooler. Would this help or harm my engine if I install this now or should I wait until I build the engine to install it?
    • 0 of 0 people found the following answer helpful

      A:  Keeping your engine at cooler temperatures is always something recommended. Honestly you could go either way as this will not harm the vehicle.

  • Q: Is this better than having no thermostat?   deom2i3 years ago

    I never use thermostat due to hot climate here (31-35c), but the car takes a long time to reach operation temperature in the morning (half way of temp gauge). Having this will help to raise the temperature and will it provide warmer engine temperature?
    • 0 of 0 people found the following answer helpful

      A:  This will help the car reach operating temperature very quickly but will keep the car cool by having a lower opening temperature.

  • Q: Temp drop  Jonlee19894 years ago

    I have a 2008 legacy get limited with everything factory other then the WRX turbo swaped on it because the factory one took a dump I live in eastern washing ton it's been 95-110 degrees F lately would this help keep it a bit cooler for the hot weather without causing it to run to cold and make it run a little rich
    • 0 of 0 people found the following answer helpful

      A:  This is not recommended for any vehicle driven on the streets and can cause issues with never reaching operating temp. If you are experiencing issues with the standard setup maintenance would be recommended first, and possibly replacing the radiator for a better unit next.

      A:  This will open up quite a bit earlier than the OEM thermostat. For daily driving, I recommend running the OEM thermostat.
