Supertech sodium-filled Inconel exhaust valve set for Subaru EJ20 and EJ25 engines. Supplied as a set of 8, these Inconel exhaust valves use sodium filling for improved heat transfer from the valve head and are specified for EJ-series exhaust ports. They suit head rebuilds or high-heat applications where a higher-temperature alloy exhaust valve is required by the engine builder.
