Supertech Mazda Miata 1.8L Inconel Exhaust Valve - +1mm Oversize - Set of 8

This is a set of eight Supertech Inconel exhaust valves, specifically designed as a +1mm oversize replacement for the 1.8L engine found in many Mazda Miata models. These valves are crucial components in your engine's valvetrain, controlling the flow of exhaust gases out of the combustion chamber.

Crafted from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures and corrosion, these valves are built to handle the demanding conditions of high-performance or heavily modified engines. The +1mm oversize design allows for increased flow potential when used with matching cylinder head modifications, potentially improving exhaust scavenging and overall engine breathing. This set includes all eight exhaust valves needed for a complete engine rebuild or upgrade.

When rebuilding the top end of your 1.8L Miata engine, using valves made from a material like Inconel ensures durability and consistent performance under high heat and stress. Always refer to the manufacturer's installation instructions for proper seating and valve guide compatibility.
