The chrome-polished stem reduces friction as the valve moves through the guide, which matters for both long-term wear and consistent valve action at higher RPM. That polished finish isn't just cosmetic, it's a real functional detail that affects how the valve performs under sustained use. It's the kind of upgrade that quietly does its job without ever needing a second thought.\u003c\/p\u003e\n\n\u003ch3\u003eSold Individually for Flexible Builds\u003c\/h3\u003e\n\u003cp\u003eThis valve is sold individually rather than as a matched set, giving you the flexibility to replace just the valves that actually need attention rather than buying a full set unnecessarily. That's particularly useful when doing a partial head rebuild or replacing a single damaged valve. Confirm the exact quantity and head size you need for your specific build before ordering. That's real, functional engineering, not just a marketing claim.\u003c\/p\u003e\n\n\u003ch3\u003eStraight From Subispeed\u003c\/h3\u003e\n\u003cp\u003eA precision 33mm exhaust valve for 2002-2014 WRX \/ 2004-2015 STI — sold individually for flexible head rebuild planning.\u003c\/p\u003e\n\n\u003cp\u003eThis Part Fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2002-2014\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2015\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eSTI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"GSC Power Division","offers":[{"title":"Default Title","offer_id":53062354862369,"sku":"GSC2013-01","price":21.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/15fb1e27-708d-4e9c-b0a7-8bff103d1b36-800_41ef70d6-16ca-432b-a51c-8620704dd362.jpg?v=1784692415","url":"https:\/\/www.subispeed.com\/products\/gsc-p-d-subaru-subaru-ej205-ej207-ej257-chrome-polished-exhaust-valve-33mm-head-1mm-single","provider":"SubiSpeed","version":"1.0","type":"link"}
