Description
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.

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.

Thermostatic Sandwich 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: Mishimoto Thermostatic adaptor plate.   longboardtipme 3 months ago

    Answer

    I have a 2005 Legacy Gt ej255. I plan on keeping the factory water to oil heat exchanger that the filter connects to. Does this plate come with the screw adapter to bolt onto the factory cooler. If not where can I source this part?


    • A: This sandwich plate is an m20 port for connecting to the cooler, it does not come with an adapter. You can find this on our site and the part number is MIS MMSPA-M20. Let us know if you have any other questions.

  • Q: Will this work on other oil cooler systems?  CHRISti 3 months ago

    Answer

    Hi I just recently bought a GSP 19 row oil cooler off of ebay, and I want to add a thermostatic sandwich plate, will this one be compatible with it?


    • A: I cannot confirm they will work together because you got the other part from Ebay and we have no record of the two being put together.

  • Q: Thermostat  Ivanski 1 year ago

    Answer

    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?


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

  • Q: adapter  caalmei40577 2 years ago

    Answer

    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?


    • 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  geemee3013143 2 years ago

    Answer

    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


    • 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.
