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":695.49,"currency_code":"EUR","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":58.85,"currency_code":"EUR","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","url":"https:\/\/www.speed-addicts.com\/en\/products\/tevi-supertech-valves-inconel-exhaust-supra-gr","provider":"Speed Addicts","version":"1.0","type":"link"}
