1400HD -21cc Piston for Mitsubishi DSM 7 Bolt and Evo 4G63 by Wiseco

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 ang 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

• Precision machined ring grooves with proper orifice/accumulator volume.
• Complex piston skirt profiles that reduce power robbing friction.
• Piston crown shapes designed to promote maximum intake charge efficiency.
• Provides maximum ring seal to prevent blow-by and minimize oil consumption
