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

If you're rebuilding the top end of your Honda H22A1 or H22A4 engine, especially for performance applications, these Supertech Inconel exhaust valves are a solid choice. They are designed to handle the extreme heat and stress found in high-performance engines, making them a reliable option when you need your engine to perform at its best.

These valves are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to high temperatures. This material is crucial for exhaust valves, as they are exposed to the hottest gases in the combustion chamber. The fact that these are +1mm oversize means they are slightly larger than stock, which can help improve sealing and potentially increase airflow when used with matching cylinder head modifications. This specific valve is for a single cylinder, so be sure to order the correct quantity for your engine.
