Dorch Engineering, in collaboration with Kelford Cams, proudly offers the ultimate B58 Exhaust Camshaft upgrade for both Gen1 and Gen1.5 B58 engines. This cutting-edge camshaft combines Kelford’s proven high-performance cam profiles with Dorch Engineering’s exclusive high-lift fuel lobe, providing both optimized valve timing for airflow improvements and an impressive 40% increase in direct injection fuel flow capacity when paired with a Dorch HPFP.

Designed for BMW 340i, 440i, 540i, 740i, and other Gen1 and Gen1.5 B58-powered models, this B58 Exhaust Camshaft ensures your engine’s valvetrain performance and fueling capacity are perfectly matched for higher boost levels, ethanol blends, and big turbo upgrades. This innovative camshaft requires no upgraded valve springs and works seamlessly with factory engine management, making it a plug-and-play upgrade with OEM-like drivability.

By combining Kelford’s track-proven camshaft profiles with Dorch’s advanced fuelling solutions, the Dorch Engineering B58 Exhaust Camshaft delivers the airflow, fuel flow, and reliability needed to support record-breaking power on the B58 platform.
