Wiseco Piston & Eagle Rod Combo for Honda Acura B18 B20 w/ Vtec Head LS VTEC 81mm
Wiseco pistons 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 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.
