Ferrea Nissan VG30ET 43mm 7mm 125.85mm 20 Deg S-Flo +1mm Competition Plus Intake Valve - Set of 6

If you're rebuilding the top end of your Nissan VG30ET engine, these Ferrea Competition Plus intake valves are a solid choice. This set includes six valves, each measuring 43mm in diameter with a 7mm stem and a length of 125.85mm. They feature a 20-degree S-Flo design, which helps improve airflow into the combustion chamber. Each valve is also +1mm oversized, meaning they are slightly larger than stock to allow for a greater volume of air to enter the cylinder, which can be beneficial for performance builds.

Ferrea is known for making well-built valvetrain components, and these competition valves are no exception. They are constructed from strong materials designed to withstand the rigors of performance applications. The S-Flo design is a notable feature that Ferrea uses to optimize flow characteristics, and the +1mm sizing is a common modification for engines looking to breathe a little easier. When installing these, ensure your valve seats are properly prepared to accept the slightly larger diameter.
