Mishimoto Oil Sandwich Plate Adapter

2013–2024 Subaru BRZ / 2017–2020 Toyota 86 FA20 Engine

MMOCA-BRZ-13

Overview:

The Mishimoto Non-Thermostatic Plate and Adapter is engineered specifically for the Subaru BRZ (2013–2024) and Toyota 86 (2017–2020) equipped with the FA20 engine. Designed for enthusiasts who demand reliable oil cooling during spirited driving or track sessions, this oil sandwich plate adapter enables the seamless addition of an external oil cooler to your vehicle’s stock oil system. Whether your car is naturally aspirated, turbocharged, or supercharged, maintaining optimal oil temperatures is critical to engine longevity and performance.

This adapter plate replaces the factory oil filter mounting point, providing high-flow ports to connect aftermarket oil cooler lines without the need for drilling or tapping. It is an ideal upgrade for drivers looking to enhance their cooling system’s efficiency and protect their engine under sustained high RPM conditions.

Key Features:

Designed with precision and performance in mind, the Mishimoto oil sandwich plate adapter offers a range of features tailored for the FA20 engine platform:

• Robust CNC-machined from lightweight 6061 aluminum for durability and heat dissipation
• Non-thermostatic design ensures continuous oil flow to the cooler for maximum cooling efficiency
• M20x1.5 threaded ports compatible with Mishimoto M20 to -10AN adapters for easy hose fitting
• Includes 1/8-NPT ports for installation of temperature or pressure sensors to monitor oil conditions
• Sandwich plate adapter set and center bolt included for direct connection to the oil filter’s high-volume feed
• Compatible with both naturally aspirated and forced induction setups
• Maintains factory oil filter location for straightforward installation
• Designed to prevent oil leaks and maintain proper oil pressure under demanding conditions

Construction & Design:

The Mishimoto sandwich plate adapter is crafted from premium 6061 billet aluminum, known for its excellent strength-to-weight ratio and thermal conductivity. CNC machining ensures precise tolerances and a perfect fit to the FA20 engine’s oil filter housing. The anodized finish provides corrosion resistance and a professional appearance. The design incorporates high-flow ports that accept standard M20 fittings, allowing for versatile hose routing and compatibility with Mishimoto’s full line of oil cooler components.

Its non-thermostatic configuration is ideal for track-focused vehicles or daily drivers in warmer climates where maximum oil cooling is desired immediately upon startup. The adapter’s integrated sensor ports enable real-time monitoring of oil temperature and pressure, giving drivers critical data to safeguard their engine.

Installation & Fitment:

Installation is straightforward and requires no modifications to the engine block or oil filter housing. The sandwich plate mounts directly between the engine block and the oil filter, utilizing the factory oil filter mounting threads. The included center bolt and adapter set allow for a secure and leak-free connection to your external oil cooler lines. This plug-and-play design minimizes installation time and complexity, making it accessible for enthusiasts with basic mechanical skills.

This product fits all Subaru BRZ models from 2013 through 2024 and Toyota 86 models from 2017 through 2020 equipped with the FA20 engine. It is also compatible with the Scion FRS within the same year range.
