Wiseco HD2 Pistons Evo 4G63T 7 bolt 85.5mm 10.5:1 K668M855AP
Description
Wiseco Pistons Evo 4 5 6 7 8 9 4G63T 7 bolt 85.5mm 10.5:1 K668M855AP.
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 âÂÂCross Flowâ during intake and exhaust valve overlap.
More fuel and air equals more horsepower.
Piston domes are designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and pre-ignition.
The end product is longer engine life and increased horsepower potential.
Precision machined ring grooves with proper orifice/ accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal, and minimized blow-by and oil consumption.
