Ferrea VW BDF 32.00mm 5.95mm 102.40mm 25 Deg S-Flo Trpl Groove +1mm Comp Plus Intake Valve-Set of 12

This set includes 12 Ferrea F1987P Comp Plus intake valves, each measuring 32.00mm in diameter with a 5.95mm stem and a total length of 102.40mm. These valves are designed with a 25-degree S-Flo triple groove for improved airflow and performance in your engine build.

Ferrea is known for making well-built engine components, and these valves are no exception. The Comp Plus design indicates they are intended for engines that have been modified for increased performance, often requiring a +1mm size increase over stock to optimize breathing. The S-Flo technology is Ferrea's approach to improving valve flow characteristics, which can contribute to better cylinder filling and overall engine efficiency. These are a solid option when you're rebuilding or upgrading the top end of an engine where airflow is critical.

When installing these valves, ensure you are working with components that match the +1mm sizing. This often means using compatible valve springs and retainers designed for the increased lift and duration typical in performance applications. Always refer to your engine build specifications or manufacturer's instructions for proper installation and compatibility.
