CSF’s triple pass front mount heat exchanger w/ rock guard (Black) for B58, and B48 is built with a high-quality engineering and advanced technology process that gives owners and enthusiasts peace of mind. Their new high-performance B58 heat exchanger drastically reduces water temperatures in the charge cooling cycle, which in turn reduces and stabilizes the intake air temperatures of the engine. With many unique features, including accessories, and of course, industry-leading performance, it’s without a doubt the best option on the market for every consumer whether it be for a daily driver or a high-performance race car.
CSF BMW B58 high-performance heat exchanger's unique triple-pass flow design is another important feature. Water from the modified heat exchanger passes through the radiator three times before leaving the cooler and flowing back to the manifold charge cooler. This ensures that the heat exchanger's exit water temperature is as low as it possibly may be. Single-pass flow structures are used in both OEM and more expensive aftermarket designs.
