Supertech BMW S14 Inconel Exhaust Valve - Set of 8

Supertech Inconel exhaust valves are engineered for extreme heat and sustained duty cycles. They offer high-temperature strength, excellent oxidation resistance, and precise seat geometry for reliable sealing and durability in turbocharged, supercharged, and endurance racing applications. Key benefits include high-temperature strength and creep resistance for sustained EGT, excellent oxidation and corrosion resistance, swirl-polished heads for stable flow, and hardened tips for guide life. Made from a Nickel-Based Superalloy, they feature precision-ground seat faces and controlled stem finish. They are heat-treated for enhanced strength and wear performance. Available in flat, dished, and tulip head shapes, and OE diameter or oversize options.
