BMW M50 M52 S50 S52 Valves by Ferrea

Ferrea Competition Plus Valves are widely recognized as one of the most dependable extreme duty valves available.

Designed specifically for the BMW M50, M52, S50, and S52 cylinder heads, these high-performance valves are made from aerospace-grade alloys, including EV8-Z18, delivering the tensile strength and resilience needed for high-revving, demanding builds.

Ferrea’s exclusive two-step slow forging process optimizes the internal grain structure of the valves, resulting in minimized stress and increased durability.

Each valve undergoes a 48-hour heat treatment and stress-relief process, ensuring consistent reliability and peak molecular integrity.

With avionics-quality hard chrome plating and a specially hardened tip, these valves are built to thrive in extreme conditions, whether for street performance or racing.

Fortify your BMW M50, M52, S50, or S52 valvetrain with a Ferrea Valve Kit for superior heat resistance, enhanced durability, and greater tensile strength—perfect for performance enthusiasts and track applications.
