Supertech Nissan RB25 Inconel Exhaust Valve- +1mm Oversize - Single

This listing is for a single Supertech Inconel exhaust valve, designed to be 1mm oversize for Nissan RB25 engines. Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures, making it a solid choice for demanding engine builds where heat and stress are significant factors.

Using an Inconel valve can help maintain sealing integrity under high cylinder pressures and temperatures, which is crucial for engine performance and longevity. The +1mm oversize dimension is typically used when the valve seat has been reconditioned or replaced, allowing for a fresh sealing surface and potentially improved flow characteristics over stock dimensions. This valve is a single unit, so you'll need to order the correct quantity for your engine's needs.
