CSF Radiators BMW B58 Gen2 High Performance Heat Exchanger With Rock Guard For BMW G Series & Toyota Supra

The 2nd Gen B58 engine, found in high-performance vehicles like the BMW G20 M340i, G22 M440i, and G42 M240i, faces a common issue with its liquid-cooled charge air cooler system: rapid heat soak with no ability to recover. This results in dangerously high intake air temperatures (IATs), causing the ECU to cut power and potentially put the car into limp mode. This problem becomes even more apparent during spirited driving or track use. At the Global Time Attack Finals (Buttonwillow Raceway, 2019), several heavily modified Toyota GR Supra race cars equipped with B58 engines could only manage 2-3 laps before overheating, forcing drivers to take cool-down laps or retreat to the pits for makeshift cooling solutions like spraying water on their front-mounted heat exchangers.

The CSF B58 High-Performance Heat Exchanger is designed to solve this problem, keeping your BMW or Supra cool and performing at its best—even under demanding conditions. Whether upgrading turbos or running performance tuning software, this upgraded heat exchanger is essential for maintaining optimal performance.
