With performance and aftermarket installation in mind, we hold extremely tight tolerances on through-hole concentricity to outside diameter which minimizes the required honing time for the installer. True-to-size outside diameters minimize honing of guide bosses on cylinder heads that don't require boss service. Our guides are easier to install and shaped to improve air flow instead of just copying OEM design.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003ePart Number:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eSize:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eQuantity:\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3121-8\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eStandard\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eSet of 8\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3121\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eStandard\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3121.001-1\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e+.001\"\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3121.003-1\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e+.003\"\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ca style=\"color: #afafaf;\" href=\"https:\/\/stmtuned.com\/collections\/gsc-power-division-products\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e\nSee more GSC Products\u003c\/span\u003e\u003c\/div\u003e\u003c\/a\u003e","brand":"GSC","offers":[{"title":"Standard Set of 8 (GSC3121-8)","offer_id":50562781675862,"sku":"GSC-3121-8","price":47.57,"currency_code":"EUR","in_stock":true},{"title":"Standard Single Guide (GSC3121)","offer_id":50562781708630,"sku":"GSC-3121","price":8.86,"currency_code":"EUR","in_stock":true},{"title":"'+.001\" Single Guide (GSC3121.001-1)","offer_id":50562781741398,"sku":"GSC-3121.001-1","price":8.86,"currency_code":"EUR","in_stock":true},{"title":"'+.003\" Single Guide (GSC3121.003-1)","offer_id":50562781774166,"sku":"GSC-3121.003-1","price":8.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/GSC3121-gsc-honda-K20C1-exhaust-valve-guides-8.jpg?v=1749204706","url":"https:\/\/www.speed-addicts.com\/en\/products\/gsc3121-gsc-honda-k20c1-exhaust-valve-guides","provider":"Speed Addicts","version":"1.0","type":"link"}
