Product Description

The **Mishimoto MMOP-SPTM22 Universal 22 mm Thermostatic Oil Sandwich Plate Adapter** is a high-quality solution for adding thermostatic control to your engine's oil cooling system. CNC-machined from lightweight 6061 aluminum and finished in silver anodize, this adapter installs between the engine's oil filter mount or sandwich plate feed location, integrating a thermostat that helps manage oil flow to external coolers and aftermarket components.

During cold starts or normal operating conditions below ~180 °F, the internal thermostat remains closed, restricting flow to the cooler and allowing the engine to reach optimal temperature faster. Once the oil warms to its operating range (~180-195 °F), the thermostatic valve opens, allowing oil to circulate through external coolers - helping maintain stable oil temperatures even under heavy load, spirited driving, or track use. Two 1/8" NPT ports provide easy access for optional oil pressure or temperature sensors or additional cooler lines.

This **universal 22 mm adapter** is ideal for custom builds and performance cooling setups, giving builders flexibility to integrate oil cooling without complex modifications. The square O-ring seal and included hardware ensure a secure, leak-resistant installation. Backed by Mishimoto's Lifetime Limited Warranty, the MMOP-SPTM22 delivers precision thermal control and reliable performance for enhanced oil temperature management in a wide range of applications.
