CSF Toyota A90/A91 Supra/ BMW G-Series B58 Charge-Air Cooler Manifold- Machined Billet Aluminum

The second-generation B58 engine powering the Mk5 Supra and BMW G-Series has quickly become a dominant force in the performance scene, with enthusiasts pushing power levels beyond 1000whp. While the OEM water-cooled charge-air cooler manifold performs adequately in lightly modified setups, it begins to falter under the demands of upgraded bolt-ons, larger turbochargers, port injection systems, and extensive tuning. This limitation can restrict the engine’s ability to maintain optimal intake air temperatures during high-performance driving.

The factory intercooler assembly is also prone to heat soak in rigorous environments such as time attack, endurance racing, drag racing, and aggressive street use. Elevated intake air temperatures (IATs) often force the ECU to reduce timing or trigger limp mode to safeguard the engine, limiting overall performance. CSF’s Machined Billet Aluminum Manifold is engineered to resolve these issues, offering a durable, precision-crafted upgrade that enhances cooling efficiency and airflow capacity. This results in improved temperature management, allowing for more consistent power delivery and reliability even under extreme boost pressures.
