Ferrea Nissan TB45E 38.1mm 7.94mm 118.8mm 25 Deg Taper Flo Stk Sqr Grv Comp Plus Exh Valve-Set of 12

These are Ferrea Comp Plus exhaust valves for Nissan TB45E engines. You get a set of 12, which is what you'll need to replace all the exhaust valves in your engine. Each valve measures 38.1mm across the head, has a 7.94mm stem diameter, and an overall length of 118.8mm. The 25-degree taper on the head helps ensure a good seal against the valve seat.

Ferrea makes these valves from a strong, high-grade steel alloy that's designed to handle the heat and stress of exhaust gases. The Comp Plus line is known for being well-built and reliable for performance applications. The square groove on the stem is a detail that helps with valve retention, making sure the valve stays put under demanding conditions. These are a solid option if you're rebuilding the top end of your Nissan TB45E and want valves that can handle the job.
