GSC P-D BMW B58 Gen 1.5 S1 Camshafts 268/270 Billet w/Intake Trigger (Use w/Upgraded Turbo) - 7095S1

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.
