SupertechÂ’s sodium filled valves are made of a superior Nickel based alloy (Inconel 751 / Nimonic 80A). We specifically choose this material because this alloy offers a significant reduction in valve head temperatures. A cooler valve improves the material strength and increases the 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 isnÂ’t a cooler valve on the market. Our sodium filled valves are a great choice for todayÂ’s modern turbo engines.
