Mishimoto Thermostatic Sandwich Plate Gold FRS BRZ GT86

Mishimoto Thermostatic Sandwich Plate Gold FRS BRZ GT86 installs as a thermostatic interface for the oil cooling system to improve oil temperature control and enhance reliability during spirited driving.

This sandwich plate is designed specifically for the 2013–2020 Subaru BRZ, Toyota 86, and Scion FRS, providing a dedicated mounting point for an external oil cooler while incorporating thermostatic regulation into the factory oil system.

Why this matters:

• Vehicle-specific design — fits the stated model years of the BRZ/86/FRS to integrate cleanly with the factory oil filter location and cooling plumbing.
• Thermostatic operation — enables controlled oil flow to an external cooler based on oil temperature, helping maintain appropriate oil viscosity and protection under varying operating conditions.
• Gold finish — offers corrosion resistance and a durable surface treatment suitable for long-term use in engine bay environments.
• Mishimoto brand — engineered and produced by Mishimoto, a supplier known for focused thermal and cooling solutions for performance vehicles.

Functional overview

The sandwich-plate configuration replaces the stock filter mounting arrangement to add a thermostatic valve and a clean connection point for an external oil cooler. This allows the oil cooling system to operate with temperature-dependent routing so oil is directed through the cooler only when additional cooling is required, preserving operating temperature when conditions do not demand extra cooling.

Application and benefits

• Track and street use — supports consistent oil temperature management during extended driving or spirited sessions to promote engine durability.
• Serviceability — maintains oil filter access while adding cooler integration, simplifying routine maintenance tasks.
• System compatibility — intended to work with aftermarket external oil coolers and lines when fitted to the specified vehicles.

Quality and fit

Produced under the Mishimoto product line, the sandwich plate is built to meet the expectations of performance-oriented owners who require reliable thermal management without sacrificing service access or vehicle-specific fitment.
