Mishimoto Thermostatic Oil Sandwich Plate

Fits Most Models

MMOP-SPT

Overview:

The Mishimoto Thermostatic Oil Sandwich Plate is a precision-engineered component designed to enhance your vehicle’s oil temperature management. Crafted from lightweight yet durable 6061 aluminum, this sandwich plate integrates a built-in thermostat that controls oil flow to the cooler based on engine temperature. This feature allows your engine oil to warm up faster during startup, improving efficiency and reducing wear, especially in colder climates.

Ideal for daily drivers and performance enthusiasts alike, the Mishimoto Thermostatic Oil Sandwich Plate helps maintain optimal oil temperature, ensuring reliable lubrication and protection under varying driving conditions. Its high-flow design supports effective cooling once the engine reaches operating temperature, contributing to overall engine longevity and performance.

Key Features:

This thermostatic oil sandwich plate combines advanced materials and thoughtful engineering to deliver precise oil temperature regulation and durable performance:

• CNC-machined from 6061 aluminum for exceptional strength and lightweight construction.
• Built-in thermostat calibrated to open at 185°F (85°C), allowing oil to bypass the cooler until optimal temperature is reached.
• High-flow design ensures efficient oil circulation and cooling once the thermostat opens.
• Includes a 1/8-inch NPT port with a plug, providing versatility for installing sensors, oil feed lines, or other fittings.
• Square O-ring design ensures a secure, leak-free seal between the sandwich plate and engine block.
• Compatible with a wide range of vehicles, making it a versatile upgrade for many applications.

Construction & Design:

The Mishimoto Thermostatic Oil Sandwich Plate is precision CNC-machined from premium 6061 aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. This ensures the plate is both durable and lightweight, minimizing added weight while maintaining structural integrity. The integrated thermostat is engineered to respond accurately to oil temperature, preventing premature oil cooling and promoting faster warm-up times.

The inclusion of a 1/8-inch NPT port adds functional flexibility, allowing you to easily install temperature sensors or additional oil lines without modification. The square O-ring seal design enhances leak prevention, providing peace of mind during installation and operation.

Installation & Fitment:

The Mishimoto Thermostatic Oil Sandwich Plate is designed for straightforward installation on most vehicle models. It mounts directly between the engine block and oil filter housing, utilizing existing factory mounting points for a secure fit. No cutting, drilling, or special tuning is required for installation.

Note: For most Subaru models, installation requires the additional purchase of the Mishimoto Stainless Steel Sandwich Plate Adapter M20x1.5 to ensure proper fitment.

• Direct bolt-on design for ease of installation.
• Uses factory mounting points and oil filter housing connections.
• No modifications to engine components necessary.
