CSF 7233 High-Performance 2-Row 42mm Aluminum Radiator for 2023-2025 Toyota GR Corolla

Fits 2023-2025 Toyota GR Corolla (Circuit Edition, Core, Morizo Edition, Premium, and Premium Plus).

The CSF 7233 High-Performance Radiator is a track-ready replacement for the OE unit, engineered to manage the high thermal loads of the G16E-GTS engine. Developed with data from race teams and development partners, this radiator features a massive 42mm 2-row core that significantly increases fluid capacity over the stock system. Its 100% all-aluminum, TIG-welded construction eliminates the plastic end tanks found on factory units, ensuring long-term durability under high pressure.

This radiator utilizes CSF’s exclusive B-Tube technology, which employs a unique internal structural design to increase heat transfer surface area by approximately 15% compared to standard oval tubes. Paired with ultra-efficient 5mm multi-louvered fins, the core maximizes airflow and heat dissipation while remaining a true plug-and-play installation with no vehicle modifications required.
