BMW S68 Valve Spring Kit by Ferrea

The Ferrea Valve Spring Kit for BMW S68 engines is engineered for superior durability and performance under extreme conditions.

Factory valve springs can struggle to meet the demands of high boost, aggressive cam profiles, and sustained high RPM, leading to valve float and potential engine failure. Ferrea valve springs are designed to prevent these issues by offering increased seat pressure and improved coil bind clearance, ensuring precise valve control at all RPM ranges.

By stabilizing valve motion, these upgraded springs enhance airflow efficiency and overall cylinder head performance, allowing for higher rev limits and maximum power output. Whether you're building a high-performance street car or a dedicated race engine, Ferrea valve springs provide strength and consistency.
