Ferrea BMW S55 28mm 5.96mm 112.83mm 21 Deg Taper-Flo STD Trpl Grv Comp Plus Ext Valve - Set of 12

If you're rebuilding the top end of your high-performance BMW S55 engine, especially for competitive use or serious track time, you need valves that can handle the stress. These Ferrea Competition Plus valves are built to take on the demands of an engine like the S55, known for its power and the heat it can generate. They are designed to work with the specific cylinder head geometry of the S55, ensuring a proper seal and efficient operation under extreme conditions.

What sets these valves apart is Ferrea's Taper-Flo design and triple groove lock system. The Taper-Flo feature helps improve airflow into the cylinder by creating a smoother transition from the valve stem to the head, and the triple groove locks are a strong choice for high-lift camshafts, offering a secure connection to the valve spring and retainer. These valves are made from a high-strength material, chosen for its ability to withstand the high temperatures and pressures found in performance applications. The 28mm intake diameter and 112.83mm overall length are specific dimensions tailored for the S55, ensuring they fit right into your existing valve train setup.

When you're pushing an engine like the S55 to its limits, every component needs to be up to the task. This set of 12 valves is a well-built choice for anyone serious about getting the most out of their engine rebuild. Make sure to follow the manufacturer's installation instructions carefully to ensure proper seating and performance.
