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.
