High flow rates, durability and quality are of great concern to Supertech Performance.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBlack Nitride Coating is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese applications. The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum). Surface Finish is smoother than with chromed stems, having less friction between stem and guide. Value seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other \"explosive\" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e28.5mm Head Diameter\u003c\/li\u003e\n\u003cli\u003e5.95mm Stem Diameter\u003c\/li\u003e\n\u003cli\u003e100.1mm Length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"newdescrLC\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2020 - 2021 Toyota Supra 3.0L\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's In The Box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 - Black Nitride Intake Valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacture Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"clear\"\u003e\u003c\/div\u003e","brand":"Supertech","offers":[{"title":"Single Valve","offer_id":31387217231942,"sku":"SUP TIVN-1058","price":29.63,"currency_code":"USD","in_stock":true},{"title":"Set of 12 Valves","offer_id":31387217264710,"sku":"SUP TIVN-1058-12","price":355.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6136\/products\/supertech-13691453734982.jpg?v=1735717022","url":"https:\/\/www.maperformance.com\/products\/supertech-black-nitride-intake-valve-2020-toyota-supra-tivn-1058","provider":"MAPerformance","version":"1.0","type":"link"}
