Mitsubishi 7-Bolt 4G63Sport Compact1400HD Pistons by Wiseco

Own a7-Bolt 4G63 engine and plan on building a motor? Wiseco is proven to make some of the best pistons on the market!

Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized and piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture “cross flow” during intake and exhaust valve overlap. More fuel and air equals more horsepower!

Their pistons are designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

Features

• 2618 Aerospace Alloy for Superior Strength to Weight Ratio
