Product Description

The **Mishimoto MMOP-SPTR Universal Thermostatic Oil Sandwich Plate Adapter** is a precision-engineered solution for integrating thermostatic oil flow control into your engine's oiling system. CNC-machined from high-quality 6061 aluminum and finished in corrosion-resistant silver anodize, this adapter installs between the engine block and the oil filter housing or sandwich plate location, adding a built-in thermostat that helps regulate oil flow to external coolers based on temperature.

During cold starts and initial warm-up, the internal thermostat restricts oil flow to the cooler to help the engine reach optimal operating temperature faster. As oil reaches its operating range (~180-195 °F), the thermostat opens, allowing oil to circulate through aftermarket coolers - aiding thermal control under heavy load, spirited driving, or track conditions. The included multiple 1/8" NPT ports provide easy access for optional oil temperature or pressure sensors or additional coolant feeds.

This **universal adapter** is designed to fit engines with sandwich-style oil feed interfaces and offers builders flexibility when planning custom oil cooling systems. The square O-ring seal and included hardware ensure a secure, leak-resistant installation. Backed by Mishimoto's Lifetime Limited Warranty, the MMOP-SPTR is a reliable component for enhanced oil temperature management in performance and enthusiast applications.
