Features & Product Details

This Mishimoto Thermostatic Oil Sandwich Plate is a lightweight, high-flow sandwich plate built from 6061 Aluminum. The built-in thermostat prevents oil flow to the cooler until the engine oil reaches activating temperature, allowing for both a faster warm-up at startup and extra oil system protection in cold climates. The included 185 degree Fahrenheit thermostat can be changed with a 160 or 200 degree unit, adding unparalleled control over your desired engine oil operating temperature.

This is only the Sandwich Plate. It has M20 ports for connecting to the cooler (and 1 port for temp or a pressure gauge), but does not come with the adapter to install it on a car. You will need to purchase that separately.

Great product 2 years ago

Swapped out a non-oil cooler sandwich plate for this thermostatic one when I installed my oil cooler. This is a solid product! It seems quite durable and all the fittings/ports seal up nice leaving no leaks. Living in a cold climate and having an oil cooler for the hot summers this is a must have. I highly recommend this to anyone needing a thermostatic plate.

I installed this and the Mishimoto oil cooler last week. For the 2011 STi, In order to make ot fit I had to point this in the opposite direction from the way the Mishimoto Youtube videos recommend, add some 90 degree fittings, and adjust them so the hoses ran closer to the headers. I wrapped the hoses well with hear insulation tape. No leaks or other issues. Altogether, the whole thing works well to keep my oil cooler.

  • Q: Thermostat  Ivanski3 years ago

    From the picture I am guessing that on the side is the plugged npt port, if I am correct where does the changeable thermostat go?
    • 0 of 0 people found the following answer helpful

      A:  The side plug secures the thermostat. Removing the plug allows you to access the spring/thermostat assembly.

  • Q: adapter  caalmei405773 years ago

    I have a 2005 sti that I am rebuilding due to a spun rod bearing. I plan on deleting the oem oil cooler. What kind of sandwich plate adapter would I need to make this item work?
    • 0 of 0 people found the following answer helpful

      A:  This sandwich plate adapter will fit a 2005 STI and it has M20 x 1.5 Ports for the oil cooler lines. If you have an oil cooler that uses M20 x 1.5 lines to attach to an adapter, then you can use this.

  • Q: NPT port  geemee30131433 years ago

    The sandwich plate only has 1 npt port, currently my 2015 STI has oil temp and oil pressure sensor installed, do you have any recommendation on having those sensors installed on only one npt port? Thanks
    • 0 of 0 people found the following answer helpful

      A:  An option would be to run one of the gauges to the adapter. Then you could tap the oil galley plug for the other sensor.
