Ferrea High Performance Valve Kit, BMW S58

The BMW S58 engine can benefit from the high performance Ferrea valve kit, which includes the reliable and durable Ferrea Competition Plus Valves. These valves have earned a reputation as the industry’s most dependable extreme duty valves. To ensure their quality, special aerospace-grade alloys, including the high tensile strength EV8-Z18, are used in their manufacturing. Additionally, an exclusive two-step slow forging process is employed to promote proper grain flow and reduce any damage to the material structure. The valves are further subjected to a 48-hour heat treatment and stress-relieving process, which is critical to their molecular integrity. Finally, the valves feature avionics-quality hard chrome and a specially applied hard tip.
