Machined from lightweight 6061 aluminum, this high-flow sandwich plate makes adding an external oil cooler simple and reliable.

Vehicle-ready fit: Designed for M22 stainless steel center bolts for easy installation and durable service life. Sensor port: Integrated 1/8" NPT side port (plugged) accepts optional temp sensors or gauges for precise monitoring. High-flow design: Internal passages are optimized to maintain oil pressure and flow while routing oil to an external cooler. Lifetime warranty: Backed by the Mishimoto Lifetime Warranty for long-term confidence. Whether you’re tracking, towing, or driving in extreme climates, this thermostatic sandwich plate delivers controlled oil cooling, faster warmups, and flexible temperature management — all in a lightweight, durable 6061 aluminum package.
