GSC's super alloy exhaust valve, sized here at 32mm head diameter in the STD option, uses an upgraded alloy specifically chosen to handle that punishing environment better than a standard valve material. That material upgrade matters most on a genuinely built engine running higher boost or sustained high RPM, where a standard exhaust valve can start to show heat-related wear. That's exactly the kind of thoughtful design worth paying for.\u003c\/p\u003e\n\n\u003ch3\u003eChrome Polished for Reduced Friction, Sold Individually\u003c\/h3\u003e\n\u003cp\u003eThe chrome-polished stem reduces friction as the valve moves through the guide, supporting both longevity and consistent valve action under sustained hard use. This valve is sold individually, so confirm the exact quantity and head size you need for your specific build before ordering. It's the right choice for anyone pushing their EJ20\/EJ257 build's exhaust side harder than a standard valve was designed for. For a component this critical, that level of engineering is worth having.\u003c\/p\u003e\n\n\u003ch3\u003eStraight From Subispeed\u003c\/h3\u003e\n\u003cp\u003eA serious, heat-resistant exhaust valve upgrade for 2002-2014 WRX \/ 2004-2015 STI — sold individually for a build that's genuinely pushing exhaust-side limits.\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":53062354993441,"sku":"GSC2015-01","price":37.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/15fb1e27-708d-4e9c-b0a7-8bff103d1b36-800_2081814c-8417-4e63-99f9-4bc275b2a87a.jpg?v=1784692417","url":"https:\/\/www.subispeed.com\/products\/gsc-p-d-ej-series-ej205-ej207-ej257-chrome-polished-super-alloy-exhaust-valve-32mm-headstd","provider":"SubiSpeed","version":"1.0","type":"link"}
