Mishimoto Oil Sandwich Plate w/ Rear-Mounted Thermostat - Universal M20x1.5

This thermostatic sandwich plate installs between your oil filter housing and spin-on filter to manage oil flow to heat exchangers on performance vehicles like daily-driven Subarus or built Audi 20V engines. It ensures proper oil temperatures for engine longevity and power output with faster warm-up times and controlled cooling. The compact design works in restricted engine bays near exhaust components.

  • Compact Footprint: Measures 2.9 x 2.6 x 1.3 inches to fit confined engine bays with exhaust or accessory interference
  • Dual 1/8 NPT Ports: Allows connection of oil temperature or pressure sensors for real-time monitoring
  • Lifetime Warranty: Covers defects in materials and craftsmanship for long-term confidence
