Ferrea Nissan TB45E 39.1mm 7.94mm 25 Deg Taper Flo +1mm Sqr Grv Comp Plus Exh Valve - Set of 12

This set includes 12 Ferrea Comp Plus exhaust valves, designed for Nissan TB45E engines. Each valve measures 39.1mm in head diameter with a 7.94mm stem and a 25-degree taper seat. The '+1mm Sqr Grv' indicates a square groove for the keeper, which is 1mm larger than standard, and the 'Flo' design helps improve airflow.

These valves are built with a focus on durability and performance for your engine's top end. The Comp Plus series from Ferrea uses specific alloys and construction techniques to handle the demands of performance applications. The 25-degree taper seat is a common angle for performance valve jobs, helping to create a good seal against the valve seat. The square groove is a notable feature for securing the valve keeper, offering a solid connection.

When rebuilding or upgrading your Nissan TB45E engine, these valves are a solid option to consider for the exhaust side. Ensure you have the correct valve springs and retainers that are compatible with these valves and your specific engine build.
