Ferrea Nissan TB45E 48mm 7.94mm 118.15mm 15 Deg S-Flo +1mm Sqr Grv Comp Plus Int Valve - Set of 12

These Ferrea Comp Plus intake valves are built with a specific design for Nissan TB45E engines. The 48mm head diameter is a +1mm oversize, which can help improve airflow into the cylinder when paired with appropriate porting. The valves measure 7.94mm in stem diameter and 118.15mm in overall length, ensuring they fit correctly within the valve guides and work with your valvetrain components.

Ferrea uses a unique S-Flo (Single Groove Flow) design on these valves, which is intended to help reduce valve float and improve gas flow characteristics. The valves are constructed from high-strength steel, chosen for its durability under the heat and stress of engine operation. This well-built set of 12 valves is designed to handle the demands of a performance-oriented rebuild or a robust stock replacement.

When rebuilding the top end of your Nissan TB45E, using valves that are built to last and designed for improved flow can make a notable difference. Ensure you have the correct valve springs and retainers to match these valves for optimal performance and reliability.
