Perrin CVT Transmission Oil Cooler Kit for 2022-2026 WRX | PSP-OIL-202

PERRIN's PSP-OIL-202 replaces the factory external SPT/CVT cooler on equipped 2022-2026 WRX models with a larger front-mounted bar-and-plate core. The kit reuses the vehicle's cooler hoses and adds application-specific stainless brackets and M22 fittings, making it the correct version for SPT/CVT trims that already have the factory heat exchanger; Base models without that cooler use the separate PSP-OIL-203 full kit. Installation requires front-bumper removal and careful handling of transmission fluid. If significant fluid is lost, PERRIN directs installers to follow Subaru's factory CVT fill and level procedure before high-load driving. The cooler is not compatible with PERRIN's front-mounted engine-oil cooler or its HELLA horn bracket. No ECU or transmission calibration is required.
