Supertech Nissan RB25 DOHC NEO 30.65 (+1)x5.96x 97.65mm Inconel Exhaust Valve - Set of 12

Supertech is well-known for making performance engine components, and this set of 12 Inconel exhaust valves for the Nissan RB25 DOHC NEO engine is a prime example of their work. These valves are built to handle the demanding conditions inside a high-performance engine, especially when you're pushing the limits.

Crafted from Inconel, a high-nickel alloy, these valves offer exceptional resistance to extreme heat and corrosion. This material is crucial for exhaust valves, as they endure the hottest gases exiting the combustion chamber. The specific dimensions, 30.65mm head diameter and 97.65mm overall length, are designed to be a direct fit for the RB25 DOHC NEO, ensuring proper sealing and airflow. The +1 sizing indicates they are slightly larger than stock, often used in performance builds to improve flow.

If you're rebuilding the top end of your RB25 or looking to upgrade for better reliability under stress, these valves are a solid option. They are built to last and perform consistently, even in demanding applications.
