Supertech Honda F20C1/F22C1 Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

You get one Supertech Inconel exhaust valve, which is 1mm larger than the stock size for your Honda F20C1 or F22C1 engine. This valve is made from Inconel, a material known for its strength and resistance to high temperatures, making it a solid choice for performance builds or engines that see hard use. The +1mm oversize design can help improve airflow into the cylinder, potentially boosting performance, especially when paired with other engine modifications.

Installing these valves means you're putting in a part that can handle the heat and stress of an engine working hard. Inconel is a nickel-chromium alloy that holds up exceptionally well in extreme conditions, far better than standard stainless steel. Because these are a +1mm oversize, they are intended to be used in a rebuilt or modified cylinder head where the valve seats have been re-machined to accept the larger diameter. This ensures a proper seal and optimal performance.
