CSF A9X Supra & BMW G-Series High-Performance All-Aluminum Radiator

The CSF A9X Supra & BMW G-Series High-Performance All-Aluminum Radiator represents the pinnacle of advanced cooling technology designed specifically for the demanding requirements of modern performance vehicles. Renowned for their expertise in thermal management, CSF has developed this radiator with a focus on durability, efficiency, and seamless integration, ensuring optimal engine cooling under the most strenuous conditions.

CSF’s extensive experience with the B58 engine platform, gathered through years of collaboration with customers, race teams, and development partners, has culminated in a product that addresses the limitations of the factory cooling system. As enthusiasts and professionals alike push the boundaries of the Supra’s performance, the stock radiator’s capacity to dissipate heat effectively has become insufficient, particularly when paired with larger turbochargers generating increased thermal loads.

The factory radiator’s design, featuring a plastic tank and a single-row aluminum core with 4mm fins, provides a baseline of quality and reliability but is constrained by its 34mm thickness and limited cooling surface area. Moreover, the charge air cooler positioned directly in front of the radiator contributes additional heat, which can elevate engine coolant temperatures and potentially trigger limp mode during high-demand scenarios such as racing or spirited driving.

In response to these challenges, CSF initiated a comprehensive development program over a year ago, incorporating rigorous race testing with partners such as Titan Motorsports and Studio RSR. The outcome is a high-performance radiator that employs CSF’s latest 5mm fin technology, enhancing the heat transfer surface area by 20-25% compared to traditional designs. This innovation significantly improves cooling efficiency and thermal recovery, critical factors for maintaining engine reliability and performance.

The CSF radiator features a robust 2-row, 42mm thick aluminum core, a substantial upgrade over the original equipment. This increased core volume not only expands the fluid capacity but also enhances the radiator’s ability to dissipate heat effectively. Central to this design is CSF’s exclusive B-Tube Technology, which boosts heat transfer by approximately 15% relative to conventional oval welded tubes. Complementing this is the multi-louvered fin structure, engineered to maximize airflow through the core without compromising aerodynamic efficiency.

Constructed with 100% TIG-welded aluminum, the radiator exhibits superior structural integrity and resistance to fatigue, ensuring longevity even under rigorous driving conditions. The CNC-machined mounting brackets and OEM-style inlet/outlet fittings guarantee a precise fitment, allowing for a true plug-and-play installation that requires no modifications or cutting to the vehicle’s factory setup.

Understanding the critical demands of motorsport environments, CSF invested significant development time and testing to deliver a radiator capable of withstanding extreme conditions. Initial prototypes, featuring a 42mm 2-row core with 6.5mm fins, underwent extensive evaluation by Titan Motorsports, a leader in drag racing with one of the fastest A90 Supras globally. Their real-world testing across various competitions demonstrated consistent reductions in engine temperatures at idle and during high-load runs, validating the radiator’s performance credentials.

For road racing applications, CSF collaborated with Studio RSR, whose "Project Silver Speed" A90 Supra competes in prestigious events including the Global Time Attack series and the Pikes Peak International Hill Climb. Testing confirmed that the CSF radiator not only lowered peak engine coolant temperatures but also accelerated thermal recovery, enhancing overall vehicle reliability and driver confidence.

Prior to final production, CSF refined the design to incorporate the advanced 5mm fin technology introduced at the end of 2023. This update further increases the heat transfer surface area and thermal efficiency beyond the prototype specifications, ensuring the radiator meets the highest standards for performance and durability in the most demanding racing conditions worldwide.
