Description
Mitsubishi 4G63 Sodium Filled Exhaust Valve by Supertech
Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for todays 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 isnt a cooler valve on the market
