Product Description

The GReddy 12069001 Hi-Cap Front-Mount Oil Cooler Kit is a premium oil-cooling upgrade designed specifically for the 2015-2021 Subaru WRX and WRX STI (EJ-series turbo 2.5 L engines). Engineered to handle the elevated thermal demands of performance or track use, this kit installs a large-capacity oil cooler core up front - above the intercooler behind the grille - where it receives excellent airflow without interfering with intake or turbo plumbing. High-flow -10 AN lines and a thermostat-equipped oil-block adapter ensure efficient, regulated oil flow and temperature control from cold start to aggressive driving conditions.

Installation is straightforward and bolt-on: the kit comes complete with cooler core, adapter, braided lines, brackets, and hardware, making it accessible even for skilled DIYers. By increasing oil capacity and improving cooling, the 12069001 kit helps maintain optimal oil viscosity and reduce thermal stress - which can extend engine and oil life, improve reliability under high boost or repeated heat cycles, and support tuned or heavily driven WRX/STI builds. For enthusiasts who push their WRX/STI beyond stock limits - whether for spirited driving, track days, or turbo upgrades - this oil cooler offers a robust, engine-protecting upgrade.
