The Mishimoto thermostatic oil sandwich plate is a CNC-machined 6061 aluminum adapter with a built-in 185°F thermostat to block oil flow to an external cooler until oil reaches operating temperature. It provides a 1/8" NPT port for sensors or feeds and accepts alternative 160°F or 200°F thermostats for tailored oil temperature control while offering high-flow routing to an oil cooler when engaged.
