KS Spec Custom Wiseco H22 Forged Piston Set

Wiesco  KS Spec Custom H22 Forged Piston Set     Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. Valve pocket designs allow maximum flow around the valve, allowing the use of oversized valves and high lift cams. Piston crown shapes are designed to promote the maximum intake charge efficiency through a scavenging mixture ‘Cross Flow’ during intake and exhaust valve overlap. More fuel and air equals more horsepowe
