Mishimoto Silver M20 Oil Sandwich Plate for 1985-1991 BMW E30 325e/i/is and E28 528e/535i

This Mishimoto Silver M20 Oil Sandwich Plate installs between the oil filter and engine block on BMW M20-equipped vehicles to control oil flow to external coolers. It blocks cold oil from the cooler until the engine reaches operating temperature providing essential protection during winter starts and extended cold weather driving. The high-flow design ensures unrestricted oil circulation once warmed delivering reliable performance for BMW E30 3-Series and E28 5-Series models.

Key Features

  • Thermostatic Control: Integrated switch opens at 185°F (85°C) and closes at 176°F (80°C) to direct oil only to the cooler after warmup preventing overcooling and viscosity issues in low temperatures
  • High-Flow Passages: CNC-machined channels maintain full oil pressure and volume without restriction supporting turbo or high-output M20 engine builds
  • Billet 6061-T6 Aluminum: Lightweight at 12.8 oz construction adds minimal weight while resisting corrosion and handling high oil pressures
  • Silver Anodized Finish: Durable hard-anodized surface protects against wear and complements engine bay aesthetics on classic BMWs
  • M20 Thread Compatibility: Direct bolt-on replacement for stock plate with 3/4-16 AN ports for easy oil cooler hose connections

Product Notes

  • Verify oil cooler line fittings match 3/4-16 AN ports before installation
  • Apply thread sealant to all fittings to prevent leaks
  • Packaged in protective foam-lined box for safe transit

Installation Notes

  • Professional installation recommended.
  • Drain engine oil torque to 25 ft-lbs using OEM torque specs for mounting bolts
  • Hardware included compatible with factory M20 oil filter housing no modifications required
