GSC7092S1 BMW B58 Gen 1 Billet Camshaft Set
Engineered for high-horsepower BMW B58 Gen 1 applications using Double VANOS and Valvetronic variable lift technology.
The GSC Power-Division S1 billet camshaft set is designed for serious turbocharged B58 combinations producing 500-900 WHP. The S1 profile increases airflow and cylinder filling in the upper RPM range while maintaining OEM Double VANOS and Valvetronic functionality.
Developed for street, Track Days, and drag racing applications, these camshafts extend the usable powerband beyond the limitations of the factory camshafts, allowing larger turbocharger systems to operate more efficiently at elevated engine speeds but keeping spool quick and responsive.
