Each valve is manufactured from premium, heat-resistant stainless steel to ensure reliability in high boost and\/or high RPM applications. The undercut stem above the head not only reduces overall weight for increased RPM potential, but also significantly improves air\/fuel flow in and out of the combustion chamber. Each valve is fully machined and features a spiral polished finish on the underside of the head.\u003c\/p\u003e\n\n\u003cp\u003eHead Diameter: 36mm\u003c\/p\u003e\n\n\u003cp\u003eStem Diameter: 5.48mm\u003c\/p\u003e\n\n\u003cp\u003eOverall Length: 108.85mm\u003c\/p\u003e\n\n\u003cp\u003eMaterial: Stainless Steel\u003c\/p\u003e\n\n\u003cp\u003eValve Type: Intake \/ Concave\u003c\/p\u003e","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":56965472387412,"sku":"USA-BC3044","price":183.12,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/4701\/3460\/files\/zestaw-zaworow-dolotowych-bc-brian-crower-bc3044-36mm-honda-acura-k20a2-k20a-k24a2_435c9bbc-de48-400d-bfa7-ee06af7dc7ab.jpg?v=1788406748"},{"product_id":"valvula-de-escape-supertech-nitrurada-en-negro-para-toyota-supra-2jzge-gte-3-0l-94-98-1-mm","title":"SuperTech Black Nitrided Exhaust Valve for Toyota Supra 2JZGE \/ GTE 3.0l 94-98 (+1mm)","description":"\u003cp\u003eBlack Nitrided Exhaust Valve\u003c\/p\u003e\n\n\u003cp\u003eHead Diameter: 30.00mm (+1.0)\u003c\/p\u003e\n\n\u003cp\u003eMaterial: 23-8N Stainless Steel\u003c\/p\u003e\n\n\u003cp\u003eGroove Type: Single Groove\u003c\/p\u003e\n\n\u003cp\u003eLength: 99.10mm\u003c\/p\u003e\n\n\u003cp\u003eStem Diameter: 5.97mm\u003c\/p\u003e\n\n\u003cp\u003eEngines\u003c\/p\u003e\n\n\u003cp\u003eToyota - 3SGTE\u003c\/p\u003e\n\n\u003cp\u003eToyota - 2JZ-GTE DOHC\u003c\/p\u003e\n\n\u003cp\u003eToyota - 2JZ-GE\u003c\/p\u003e\n\n\u003cp\u003eManufacturer: SuperTech\u003c\/p\u003e\n\n\u003cp\u003eSKU: USA-ST-TEVN-1016\u003cbr\u003e\nThese images are representative;
