A single chrome-polished exhaust valve for Subaru EJ205, EJ207 and EJ257 engines with a 33mm head, listed as +1mm oversize. This option is suitable when head work requires an oversized exhaust valve for improved flow or to match port modifications. Offered individually for rebuilds and performance head assemblies, the polished finish supports sealing while the +1mm diameter provides an upgrade path when larger exhaust valves are needed for tuned EJ engines.
