Ferrea High Performance Valve Kit, BMW M40/M42/M43/M44
The Ferrea Competition Plus Valves are highly regarded as one of the most reliable extreme duty valve kits in the industry. Specifically designed for the classic BMW M40, M42, M43, and M44 engines, these valves are crafted with performance in mind, using aerospace-grade alloys such as EV8-Z18 for maximum tensile strength.
Ferrea’s unique two-step slow forging process ensures superior grain flow, enhancing the structural integrity of each valve. A 48-hour heat treatment and stress-relieving procedure ensures the molecular integrity of the valves, allowing them to withstand the intense demands of high-performance use. Finished with avionics-quality hard chrome plating and featuring a specially hardened tip, these valves are manufactured to perform under the toughest conditions.
Upgrade your BMW M40, M42, M43, or M44 engine with the Ferrea Valve Kit and experience increased durability, improved heat resistance, and enhanced performance—ideal for everything from high-performance street builds to motorsport use.
