Mishimoto Thermostatic Gold M20 Oil Sandwich Plate

Whether you have a daily driven Subaru or a built Audi 20V, proper oil temperatures are crucial for engine longevity and performance. Keep your temperatures in check with the Mishimoto thermostatic sandwich plate. This high-flow sandwich plate is constructed from lightweight CNC-machined billet 6061 aluminum, providing unmatched precision and quality. The internal oil thermostat will restrict flow to your heat exchanger until the activation temperature is reached; this provides improved warm-up while maintaining efficient cooling properties. Thanks to a small footprint and rear-mounted thermostat, the Mishimoto sandwich plate can be installed in even the tightest engine bays where the exhaust or other engine components create strict space constraints. This sandwich plate includes two 1/8 NPT ports for use with temperature or pressure sensors. As with all our products, this sandwich plate includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
High-performance component designed to enhance thermal efficiency, durability, and reliability under demanding conditions. Engineered to support optimal temperature control and system performance across applications.
Universal Fitment

• Two 1/8-in NPT ports (with plug) for sensors/oil feed/etc
