Supertech Honda H22A1/H22A4 Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

Made from Inconel, a high-nickel alloy, this Supertech exhaust valve is built to handle extreme temperatures. This particular valve is a +1mm oversize option, meaning it's slightly larger than the stock valve. This can help improve flow and performance when rebuilding or modifying your Honda H22A1 or H22A4 engine.

The Inconel material is chosen for its exceptional resistance to heat and corrosion, which is critical for exhaust components that endure the hottest gases in your engine. This single valve is a direct replacement for one exhaust valve in your engine, and it's designed to fit right into the stock valve seat. If you're working on a performance build or replacing worn-out valves, this oversize option can be a solid choice for improved engine breathing.
