CSF 2023+ Toyota GR Corolla/2020+ GR Yaris High Performance Stepped Core Intercooler System - Silve

When you're pushing your 2023-2025 Toyota GR Corolla hard, especially on track or during spirited driving, managing intake air temperatures becomes critical. The factory intercooler can reach its limit relatively quickly, leading to heat soak and a drop in performance. This CSF High Performance Stepped Core Intercooler System is designed to significantly improve your GR Corolla's ability to keep those intake air temperatures down, even under demanding conditions.

This intercooler features a unique stepped core design, which CSF selected for its excellent cooling efficiency and lighter weight compared to bar-and-plate designs. This means you get a 45% larger core volume and 73% more surface area than the stock unit, allowing it to absorb and dissipate more heat. The tube-and-fin construction is chosen for optimal airflow, and the TIG-welded cast aluminum end tanks are much stronger and more durable than the factory's crimped plastic ones, ensuring it can handle high boost pressures reliably over time. To match the intercooler's increased capacity, the kit includes motorsport-grade 5-ply silicone hoses that step up from the factory 1.85-inch diameter to a larger 2.5-inch diameter, connecting to your factory charge pipes.

CSF has made this a true plug-and-play installation, mounting in the factory location without needing modifications to the bumper or crash bar. You will need to trim the factory air ducting to properly guide air into the upper stepped core, but the hoses and clamps are designed to handle extreme boost. This intercooler has been real-world tested and proven to reduce charge air temperatures by over 240ºF, which is a substantial improvement over the stock unit, helping to keep your engine running strong and consistently.
