Sodium Filled Valves

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines. 

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
