Ferrea Competition Plus Valves are celebrated for their extreme duty performance and industry-leading reliability. Designed specifically for the BMW N55 and S55 engines, these valves are crafted from aerospace-grade alloys like EV8-Z18, delivering superior tensile strength and exceptional durability for high-performance applications.

Ferrea's two-step slow forging process ensures optimal grain flow and minimizes internal stress, providing unmatched durability for your engine. Each valve undergoes a rigorous 48-hour heat treatment and stress-relief process, ensuring optimal molecular integrity. Finished with avionics-grade hard chrome plating and featuring a specially hardened tip, these valves are engineered to withstand the extreme demands of performance use.

Upgrade your BMW N55 or S55 engine with the Ferrea Valve Kit for greater strength, improved heat resistance, and outstanding reliability—perfect for both street performance and motorsport builds.
