GSC P-D Nissan TB48DE Stainless Steel Exhaust Valve 34.50mm Head (+1mm) - Single

What you get here is a single exhaust valve from GSC Power Division, specifically made for Nissan TB48DE engines. This valve has a 34.50mm head diameter, which is a full millimeter larger than the factory size. This slight increase in head size can help improve airflow into the cylinder, especially if you're working on rebuilding or modifying the top end of your engine.

This valve is constructed from stainless steel, a common choice for exhaust valves because it holds up well to the high temperatures and harsh conditions found in the exhaust port. The material choice means it's built to handle the heat and stress of combustion. It's a well-built component designed to be a direct replacement for your stock valve, making installation straightforward if you're already inside the engine.
