Description
The Skunk2 Ultra Valve Springs and Spring Base Kit for Honda K20C1 / K20C4 engines are designed for high-performance applications that require upgraded valve springs to handle increased valve lift and higher engine speeds. The kit features specially engineered, ultra-lightweight valve springs that are made from super-clean chrome silicone wire, shot-peened, and heat-treated to maximize fatigue resistance and spring life.
