The 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 warmup at startup and extra oil system protection in cold climates. The included 185°F (85°C) thermostat can be changed with a 160°F (71°C) or 200°F (93°C) unit, adding unparalleled control over your desired engine oil operating temperature.
