MIA's Description

The Wiseco 14.0:1 pistons are designed for a K20 cylinder head and K24 engine block. This kit includes 4 pistons, 4 wrist pins, 4 wrist pin locks, and 4 rings. Wiseco Sport Compact pistons are made from dedicated forgings produced in-house to give you a light weight piston with superior strength and optimal design. Being the multivalve piston technology leader, the line features specially designed valve pockets, complex dome and crown shapes, the steel nitride/napier xx rings and optimized skirt profiles. Some of our forged pistons offer our new ArmorGlide skirt coating, which is the result of testing, development, and benchmarking through Wiseco's rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock. Made from 2618 Aerospace alloy for superior strength. HD2 severe duty forging available for heavy horsepower applications. ArmorPlating available on select applications. Strutted forging for improvised strength. Performance piston ring set included.
