SKU: N/A Category:


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.
