Ferrea Nissan VQ35 6mm Viton Hi-Temp Exhaust Valve Stem Seal - Single (Drop Ship Only)

Ferrea is known for making high-performance engine components, and this single exhaust valve stem seal is no different. This seal is specifically designed for Nissan VQ35 engines and uses a 6mm stem size. It's made from Viton, a material that can handle high temperatures, which is crucial for exhaust valve applications where heat can be intense.

Replacing valve stem seals is a common job when you're rebuilding the top end of an engine, especially if you're seeing oil burning on startup or during deceleration. These seals keep oil from leaking down the valve guide into the combustion chamber. Using a hi-temp Viton seal like this one from Ferrea helps ensure it can withstand the heat of the exhaust side without breaking down prematurely, giving you a more reliable seal over time.
