Show original supplier description
Supertech sodium-filled valves, crafted from Inconel/Nimonic alloy, significantly lower valve head temperatures crucial for modern turbo engines. This cooling effect enhances material strength and durability, providing tuners with greater flexibility for spark timing advancements. These valves also boast an average 10% weight reduction.
