Perrin Oil Temperature and Pressure Adapter 2015-2025 WRX / 2013-2025 BRZ / 2013-2025 Crosstrek / 2013-2025 Forester / 2013-2018 Forester XT / 2013-2025 Impreza / 2013-2025 Legacy / 2013-2025 Outback | Dual Sensor Ports | Oil System Adapter
Overview
The Perrin Oil Temperature and Pressure Adapter is a precision-engineered solution designed to simplify the installation of aftermarket oil temperature and pressure sensors on a wide range of Subaru models. This adapter eliminates the need for permanent modifications to your engine’s oil system, providing a clean and reversible way to monitor critical oil parameters. It is ideal for Subaru enthusiasts who want accurate oil readings for tuning, maintenance, or track use without compromising engine integrity.
Crafted from 6061 billet aluminum and finished with a durable black anodized coating, this adapter reflects Perrin Performance’s commitment to quality and functional design. Unlike universal adapters that often interfere with engine components due to insufficient clearance, this model is raised to ensure sensors fit properly without obstruction. The inclusion of two NPT-type ports allows simultaneous installation of both oil temperature and pressure sensors, with plugs provided if only one sensor is used.
By measuring oil temperature before the cooler, this adapter provides a reading that closely matches the oil pan temperature, widely regarded as the most accurate reference point for oil temperature monitoring. This precise data is invaluable for Subaru owners focused on engine health, performance tuning, or track reliability, making the Perrin adapter a practical upgrade for WRX, STI, BRZ, Crosstrek, Forester, Impreza, Legacy, and Outback platforms.
