- 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.
