Supertech Nissan RB26 31.15x6.94x101.20mm Inconel +1mm Exhaust Valve - Single (Drop Ship Only)

If you're rebuilding the top end of a Nissan RB26 engine, especially for performance builds, you'll want to consider these Supertech Inconel exhaust valves. These valves are specifically made to handle the intense heat and stress found in high-output RB26 engines, helping to ensure reliable operation under demanding conditions.

Crafted from Inconel, a high-nickel alloy, these valves offer exceptional resistance to extreme temperatures and corrosion. This material is crucial for exhaust valves, as they endure the hottest gases exiting the combustion chamber. The +1mm sizing means these valves are slightly larger than stock, which can help improve flow and sealing when used with appropriately modified cylinder heads. Each valve is sold individually, so you can purchase exactly what you need for your rebuild.
