OVERVIEW

Keep intake air temperatures under control and combat heat soak with the CSF High Performance Stepped Core Intercooler System for the 2023+ Toyota GR Corolla (GZEA14H) and 2020+ GR Yaris (GXPA16). Co-engineered with Jackson Racing, this drop-in upgrade features an innovative stepped-core design that maximizes all available space behind the front bumper—delivering a massive 45% increase in core volume and a 73% increase in surface area without requiring bumper trimming or crash bar removal. Finished in a stealth black coating, this kit includes upgraded 2.5-inch 5-ply silicone hoses and heavy-duty clamps to handle high boost loads on track and street.
