Supertech Mazda FS/Protege 2.0L Inconel Exhaust Valve - +2mm Oversize - Set of 8

These are Supertech Inconel exhaust valves, designed as a +2mm oversize set for Mazda FS and Protege 2.0L engines. If you're rebuilding the top end of your engine, especially if it sees hard use or you're looking for improved durability, these valves are a solid option. They are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme heat and corrosion, making them ideal for exhaust applications where temperatures can get very high.

The +2mm oversize design means these valves have a slightly larger diameter than stock. This can help improve flow into the cylinder, and when paired with matching port work, can contribute to better performance. The Inconel material itself is a significant upgrade over standard steel valves, offering much better longevity under demanding conditions. This set includes all eight exhaust valves needed for a complete engine rebuild.
