The Racer X Fabrication thermostatic oil adapter plate kit for the 2023+ Toyota GR Corolla is available as a separate kit for those that would like to build their own oil cooler kit. The adapter plate is CNC machined from 6061-T6 aluminum. The thermostatic adapter plate uses a square profile o-ring for a perfect seal to the OEM oil filter location. The 3/4"-16 threaded adapter mates to the oil filter location and retains the same diameter and pitch for the oil filter to be placed on top. The thermostatic adapter plate uses a 185F thermostat that allows oil temperatures to raise to the operating range before diverting oil through the cooler. The adapter plate comes standard in black anodize.
