The Racer X Fabrication intercooler for the 2023+ Toyota GR Corolla was developed to decrease charge air temps and improve performance. The Racer X intercooler uses a high density Garrett intercooler core to provide optimal cooling during spirited driving or track use. The end tanks are CNC laser cut from 5052 aluminum sheet, then formed on a CNC press brake to ensure consistent and repeatable bends. The inlet and outlet on the end tank are CNC turned from 6061-T6 aluminum, feature a coupler retention lip, and a generous radius to transition airflow into and out of the intercooler tanks. The completed components are then precision TIG welded for a complete intercooler assembly that is ready to perform. During intercooler testing we saw gains of 10-15 wheel horsepower and 10-15 lb-ft of torque through most of the RPM range. The Racer X intercooler provided on average 20°F lower charge air temps when compared to the OEM intercooler.
