CSF Toyota A90/A91 Supra/ BMW G-Series B58 Charge-Air Cooler Manifold- Black

The second-generation B58 engine, featured in the Mk5 Toyota Supra and BMW G-Series, has rapidly established itself as a powerhouse in the performance and motorsports world. Enthusiasts are routinely pushing these engines past the 1000whp mark, and the OEM charge-air cooler manifold struggles to keep up under high-performance demands. While the factory water-cooled manifold performs adequately on lightly modified vehicles, it quickly reveals its limitations with common bolt-on upgrades, turbo enhancements, port injection, and aggressive tuning.

The OEM intercooler setup also experiences significant heat soak during intense racing scenarios such as time attack, endurance events, drag racing, drifting, and spirited street runs. This excessive heat leads to elevated intake air temperatures (IATs), causing the ECU to reduce timing and, in severe cases, trigger limp mode to protect the engine. The CSF Black Charge-Air Cooler Manifold addresses these issues with a precision-machined design that optimizes airflow and cooling efficiency, providing the stability and durability required to support extreme boost levels and maximize performance without compromise.
