BMW M52TU M54 Valve Set

This race-ready BMW M52TU M54 Valve Set from Manley Performance is engineered specifically for high-demand builds. With single-groove stems, and offered in a robust 6 mm stem diameter, these stainless steel valves are ideal for aggressive cam profiles, high-RPM operation, forced induction, nitrous, or any build where durability and flow matter.

Constructed from premium stainless steel alloys, the intake valves are swirl-machined and polished to exacting tolerances while the exhaust valves are hardened for exceptional resistance to elevated temperatures and extreme combustion pressures. Each valve features a precision back-cut under-head profile to optimize airflow and maximize volumetric efficiency in upgraded cylinder heads. Hardened tips and durable stem materials deliver long-term wear resistance and maintain performance under severe duty cycles.
