Ferrea Nissan TB45E 47mm 7.94mm 118.15mm 15 Deg S-Flo Stock Sqr Grv Comp Plus Int Valve - Set of 12

This set includes 12 Ferrea Comp Plus intake valves, specifically made for Nissan TB45E engines. These valves feature a 47mm head diameter and a 7.94mm stem diameter, with a total length of 118.15mm. The 15-degree S-Flo design with a square groove helps improve airflow into the cylinder.

Ferrea's Comp Plus valves are well-built for performance applications. They are constructed from high-grade materials designed to withstand the heat and stress of engine operation. The S-Flo design is notable for its ability to reduce turbulence and increase the velocity of the air-fuel mixture entering the combustion chamber, which can lead to improved engine response.

If you're rebuilding the top end of your Nissan TB45E, these valves are a solid option. They are designed as a direct replacement for stock valves, simplifying installation. Ensure you have the correct valve springs and retainers for your application to match these performance valves.
