Product Description

The PERRIN PSP-OIL-151 Top-Mount Oil Cooler Kit is designed for 2015-24 Subaru WRX owners looking to improve oil cooling performance. By mounting the cooler beneath the hood scoop, it efficiently uses airflow to maintain optimal oil temperature under high-stress driving conditions, including track use, heavy boost, or performance tuning.

Installation replaces the OEM oil cooler and routes supplied hoses alongside the strut brace. The kit is compatible with manual transmissions and requires a 1" (25 mm) strut-bar and an aftermarket front-mount intercooler. Approximately 0.5 L of engine oil should be added post-installation. This kit provides a reliable, long-term solution for maintaining engine health in performance WRX applications.
