Ferrea Nissan NEO 35.15mm 5.98mm 104.2mm 20 Deg S-Flo +1mm Competition Plus Intake Valve - Set of 12

This set includes 12 Ferrea Competition Plus intake valves, each measuring 35.15mm in diameter with a 5.98mm stem and a total length of 104.2mm. They feature a 20-degree S-Flo design and are enlarged by +1mm over stock to help your Nissan engine breathe better.

When you're rebuilding the top end of your Nissan engine, especially for performance applications, the intake valves play a crucial role in how much air can enter the combustion chamber. Ferrea's Competition Plus valves are forged from high-strength steel, making them a solid choice for engines that see demanding use. The S-Flo design is a notable feature that helps improve airflow characteristics into the cylinder, which can lead to better performance. The +1mm sizing means these valves are slightly larger than stock, allowing for potentially more air volume to enter the engine, especially when paired with other modifications.

These valves are a direct replacement for stock, but it's always a good idea to consult your engine builder or a trusted mechanic to ensure they are the right fit for your specific build and to confirm any necessary machining or component compatibility.
