BMW M50 Non-VANOS Valve Set

This race-ready BMW M50 Non-VANOS Valve Set from Manley Performance is engineered for high-demand builds. Designed with single-groove stems and offered in 7-mm stem diameter, these stainless steel valves accommodate aggressive cams, forced induction, and sustained high-RPM operation.

Crafted from premium stainless steel alloys, the intake valves are polished, swirl-machined and built to exacting tolerances; the exhaust valves are hardened for extreme heat resistance. Each valve features a precision back-cut profile to optimize airflow and maximize volumetric efficiency in tuned cylinder heads. Hardened valve tips and durable stems ensure these valves withstand the high loads, elevated temperatures and severe duty cycles found in drag racing, road racing and high-horsepower turbo builds.

Key Features:

• Single-groove stem design for secure keeper retention
