Supertech Nissan SR20DET 31.15X6.94X102.40mm +1mm Inconel Exhaust Valve - Set of 8 - NEVI-1007-7-8
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
