Description
The Mishimoto Thermostatic Oil Sandwich Plate (MMOP-SPT) is a purpose-built engine component engineered to give your oil cooling system real thermal control. Machined from 6061 aluminum and finished in gold, this sandwich plate houses a built-in 185°F thermostat that can be swapped for a 160°F or 200°F unit, letting you dial in exactly how your car engine manages oil temperature.
Among the many parts of a car engine, the oil circuit is one of the most overlooked, yet it plays a critical role in protecting internals during startup and sustained operation. This thermostatic sandwich plate blocks oil flow to the cooler until the oil reaches its activation temperature, which shortens warmup time and adds a layer of protection in cold climates. As one of the more specialized components of an automobile engine, it bridges the oil filter and cooler, giving enthusiasts who care about engine parts and components of automobile engine performance a simple way to fine-tune oil temperature control across different driving conditions and climates.
Vehicle Applications
The Mishimoto MMOP-SPT is designed as a thermostatic oil sandwich plate for engines equipped with an oil cooler system, mounting between the oil filter and the block using a square O-ring design and included gasket/seal. Specific make, model, and year fitment details were not provided in the available product data, so installers should confirm compatibility of the sandwich plate’s port and O-ring configuration with their particular oil filter and cooler setup before installation.
