Ferrea VW BDF 33.00mm 5.95mm 136.70mm 25 Deg S-Flo Trpl Groove +2mm Comp Plus Intake Valve-Set of 12

Ferrea offers a set of 12 Comp Plus intake valves designed for VW BDF engines. These valves feature a 33.00mm head diameter and are +2mm oversized compared to stock, which can help improve airflow into the combustion chamber. The valves measure 136.70mm in overall length with a 5.95mm stem diameter and a 25-degree seat angle.

These valves are built with Ferrea's S-Flo design, which aims to optimize flow characteristics. The triple groove stem design is intended for use with specific valve locks and retainers, ensuring a secure fit. The Comp Plus series is known for its robust construction, suitable for performance applications where increased cylinder pressure and higher RPMs are common. The +2mm oversizing is a notable change that can contribute to improved engine breathing, especially when paired with other engine modifications.

When rebuilding or modifying a VW BDF engine, selecting high-performance valvetrain components like these Ferrea valves is important for achieving optimal results. Ensure you have the correct valve locks, retainers, and seals that are compatible with the 5.95mm stem diameter and the +2mm oversized head.
