Designed for high-performance applications, these Supertech +1mm oversize exhaust valves are specifically engineered for Honda K20, K24, F20C1, and F22C1 engines. Built to withstand the extreme thermal loads found in turbocharged, supercharged, or high-compression racing builds, these valves provide the heat resistance and flow capacity required for maximum power output.

These valves are manufactured from Inconel 751, a nickel-based superalloy that maintains its structural integrity at temperatures where standard stainless steel begins to fail. Each valve is forged, CNC-machined, and features a chrome-plated stem for reduced friction and extended guide life. Note that the +1mm oversize diameter requires professional cylinder head machine work to enlarge the valve seats.
