Description
Upgrade the cooling performance and thermal efficiency of your BMW B58 with the CarBahn Performance Heat Exchanger Kit. Designed specifically for BMW M240i, M340i, and M440i models, this high-performance heat exchanger utilizes advanced Formula 1-derived heat exchanger technology to increase cooling capacity and improve charge air temperature management.
CarBahn has engineered this heat exchanger to provide a 40% increase in cooling capacity. As boost pressure increases, the engine generates additional heat. The upgraded heat exchanger helps reduce charge air temperatures, providing increased thermal headroom for higher-boost applications and helping support more consistent power output.
Lower charge air temperatures can also contribute to increased power, with the benefits becoming particularly noticeable during summer months and high ambient temperature conditions where heat soak can have a greater impact on engine performance.
The heat exchanger utilizes race-car-inspired technology designed for significantly improved thermal efficiency compared with lower-cost aftermarket heat exchangers. Its lightweight construction also provides a significant weight advantage compared with traditional race-car heat exchanger designs.
When used in conjunction with CarBahn performance software, the heat exchanger provides additional thermal safety margin, allowing CarBahn to offer a factory-matching warranty on the engine and drivetrain, subject to applicable CarBahn software and warranty terms.
