S58
Taking the BMW S58 to the Next Level
The S58 engine is the pinnacle of BMW’s modern straight-six development. Powering the G80 M3, G82 M4, and the latest M2, this twin-turbocharged beast is a racing engine for the road. While the factory S58 is already incredibly powerful, Kelford Cams has developed valvetrain components for the owner who wants to lead the pack. Our S58 range is built for those who demand the absolute maximum from their M-Power machine.
Engineered for Elite M Performance
The S58 thrives at high RPMs, which places unique demands on the camshafts and valve springs. Kelford technicians have designed S58 profiles that optimize the power band for both high-end speed and mid-range response. By improving the engine’s ability to move air under high boost, our cams allow you to reach higher horsepower figures more safely. Whether you are building a time-attack monster or a world-record-breaking drag car, our S58 parts provide the mechanical reliability you need.
