Supertech Mazda Miata 1.8L Inconel Exhaust Valve - +1mm Oversize - Single

This listing is for a single Supertech Inconel exhaust valve, designed for the 1.8L engine found in the Mazda Miata. It's a +1mm oversize valve, meaning it's slightly larger than the stock size, which can be beneficial when rebuilding or modifying the engine's top end.

The valve is constructed from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures and corrosion. This makes it a solid choice for high-performance applications or engines that see a lot of heat, like those with forced induction or aggressive tuning. The +1mm sizing is useful for engines that have been bored out or require a larger valve for improved flow.
