B58 Gen 1.5
Unleashing the First Generation B58
The first generation of the BMW B58 engine brought the B-series modular architecture to the masses, providing a sturdy foundation for the F30, F32, and F20 chassis. While later versions of the B58 introduced different cooling and fuel system layouts, the Gen 1 remains a favorite for tuners. Kelford Cams provides specialized camshafts and valvetrain components specifically for these early B58 units, helping you unlock power that the factory never intended.
Custom Profiles for F-Series Owners
Our B58 Gen 1 camshafts are designed by Kelford technicians who understand the nuances of the early 3.0L B-series head. By increasing the duration and lift, we allow the engine to pull harder through the mid-range and hold its power much longer toward the redline. This is particularly effective for those who have upgraded their turbochargers and find the factory cams are holding back the engine’s true potential.
