The Mishimoto Oil Sandwich Plate with Rear-Mounted Thermostat is designed to optimize oil temperature regulation for a variety of vehicles, from daily drivers like Subaru to performance builds such as Audi 20V. Crafted from lightweight CNC-machined billet 6061 aluminum, this high-flow sandwich plate offers exceptional durability and precision engineering. The integrated thermostat activates at 185°F (85°C), restricting oil flow to your heat exchanger until optimal warm-up is achieved, which helps improve engine start-up and maintains consistent operating temperatures for enhanced engine longevity and performance. Its compact design features a rear-mounted thermostat and small footprint, making it suitable for installation in tight engine bays where space is limited due to exhaust components or other engine accessories. The unit includes two 1/8-inch NPT ports, allowing you to connect temperature or pressure sensors for monitoring and diagnostics, making it a versatile choice for performance enthusiasts and daily drivers alike. As with all Mishimoto products, this sandwich plate is backed by a lifetime warranty, ensuring superior craftsmanship and long-term reliability. Whether you are upgrading your cooling system or seeking more precise oil temperature management, this sandwich plate provides a reliable and efficient solution to meet your automotive needs.
