CSF High-Performance Auxiliary Radiator

2020–2024 Toyota GR Supra

8179

Overview:

The CSF High-Performance Auxiliary Radiator is engineered specifically for the Toyota GR Supra model years 2020 through 2024. Designed to enhance cooling efficiency, this radiator is ideal for enthusiasts and tuners seeking to maintain optimal engine temperatures during aggressive driving, track days, or high-performance applications. Unlike other aftermarket options that rely on the OEM plastic rock guard, CSF’s solution maximizes airflow while providing robust protection against road debris.

By addressing the limitations of the OEM rock guard’s vertical channel design—which restricts airflow when paired with aftermarket cores—CSF has developed a redesigned aluminum rock guard that ensures maximum cooling performance without compromising durability. This auxiliary radiator is a direct drop-in replacement for both the left and right sides of the vehicle, requiring no modifications for installation.

Key Features:

CSF’s auxiliary radiator incorporates advanced design and manufacturing techniques to deliver superior cooling performance and reliability. Key features include:

• Industry-exclusive detachable aluminum rock guard optimized for maximum airflow and debris protection
• 2-row, 42mm ultra-high performance core with 6.5mm tall multi-louvered fins
• Exclusive B-Tube technology for enhanced heat dissipation
• CNC machined mounting brackets for precise fitment and durability
• OEM-style “Quick Connect” inlet and outlet connections for seamless plug-and-play installation
• 100% all-aluminum TIG-welded construction for strength and corrosion resistance
• Finished in a thermal black protective coating to improve heat radiation and resist environmental wear
• Tested extensively in CSF’s in-house wind tunnel and validated by global R&D partners including leading time attack teams and turbo kit manufacturers
• Sold individually and compatible with both left and right side installation

Construction & Design:

Built with premium materials and precision engineering, the CSF auxiliary radiator features a robust all-aluminum construction that ensures long-lasting durability and efficient heat transfer. The TIG-welded core and frame provide structural integrity under demanding conditions, while the thermal black coating enhances heat dissipation and protects against corrosion. The multi-louvered fin design combined with CSF’s proprietary B-Tube technology optimizes airflow and cooling capacity, making it one of the most advanced radiators available for the GR Supra platform.

The redesigned aluminum rock guard is a standout innovation, crafted to avoid the airflow restrictions common with OEM plastic guards. This design improvement allows the radiator to perform at its full potential without sacrificing protection from small rocks and road debris.

Installation & Fitment:

The CSF auxiliary radiator is engineered as a true drop-in fit for the 2020–2024 Toyota GR Supra, compatible with both the left and right sides of the vehicle. Installation requires no modifications, preserving the integrity of your vehicle’s factory setup and any aftermarket aerodynamic components. The CNC machined mounting brackets and OEM-style quick connect fittings simplify the installation process, enabling a straightforward, plug-and-play upgrade.

For best results, follow the manufacturer’s repair manual for installation instructions. If you are not confident in performing the installation yourself, CSF recommends consulting a qualified automotive technician.
