BMW / Toyota B58 Valves by Ferrea

Ferrea Competition Plus Valves are trusted as one of the most dependable extreme duty valve kits available. Specifically designed for the B58 engine, which powers vehicles like the BMW 340i, 440i, M240i, Z4, Toyota Supra, and more, these high-performance valves are built from aerospace-grade alloys, including EV8-Z18, for superior tensile strength and durability.

Ferrea's exclusive two-step slow forging process optimizes grain flow, reducing material stress and enhancing the valves' ability to endure extreme conditions. A rigorous 48-hour heat treatment and stress-relief process guarantees the valves' molecular integrity, ensuring reliability under the most demanding environments. Finally, each valve is coated with avionics-grade hard chrome plating and features a specially hardened tip for extended lifespan.

Upgrade your B58 engine with the Ferrea Valve Kit to experience enhanced tensile strength, improved heat resistance, and exceptional durability—perfect for high-performance builds and motorsport applications where reliability is key.
