Nitride\" is a hardening treatment that is applied to the whole valve whereas the chrome coating is only applied to the stem. The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer. Microhardness is 800HV minimum.\u003cbr\u003e\u003cbr\u003eThe Black Nitride surface finish is smoother than with chromed stems, having less friction between stem and guide. The higher the engine speed the bigger the power loss due to internal engine friction!

These valves are hollow and filled with sodium, designed to withstand even higher temperatures. As the sodium becomes liquid it will transfer heat from the head of the valve to the guide and cylinder. A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market.\u003cbr\u003e\u003cbr\u003ePhotos are for reference.\u003cbr\u003e\u003ca href=\"https:\/\/stmtuned.com\/collections\/supertech-products\" style=\"color: #afafaf;\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more Supertech Parts\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"Supertech","offers":[{"title":"Standard 30.10mm Sodium Filled (Set of 12) (TEVI-1058-HS-12)","offer_id":50563022389590,"sku":"SUP-TEVI-1058-HS-12","price":649.51,"currency_code":"USD","in_stock":true},{"title":"Standard 30.10mm Sodium Filled (1 Single) (TEVI-1058-HS-1)","offer_id":50563022422358,"sku":"SUP-TEVI-1058-HS-1","price":54.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/TEVI-supertech-valves-inconel-exhaust-supra-gr-set-of-12.jpg?v=1749207890"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/collections\/Supertech_logo.webp?v=1779897665","url":"https:\/\/www.speed-addicts.com\/en\/collections\/supertech.oembed","provider":"Speed Addicts","version":"1.0","type":"link"}
