Supertech Nissan 350Z VQ35 Black Nitrided Exhaust Valve- +1mm Oversize - Set of 12

These Supertech exhaust valves are black nitrided, a surface hardening process that makes the valve face more durable and resistant to wear. This set includes 12 valves, each measuring 1mm oversize, designed to fit Nissan 350Z models with the VQ35 engine. The +1mm oversize dimension is useful when rebuilding an engine where the valve seats may have been re-ground or if you're looking for a slightly larger valve to improve flow.

The black nitriding process not only improves hardness but also helps reduce friction, which can contribute to better valve sealing and longevity. Supertech is known for making well-built internal engine components, and these valves are a solid option for anyone rebuilding or upgrading their VQ35 engine. They are designed to be a direct replacement for your stock valves, making installation straightforward as part of a larger cylinder head job.
