Wiseco K20/24 87.5mm Bore Pistons at 10.2:1 compression are engineered for extreme boost applications and nitrous oxide use. This four-piston assembly includes wrist pins, retaining locks, and complete ring sets for ready installation. Precision-forged from dedicated in-house stock, these pistons deliver exceptional strength while maintaining minimal weight for responsive performance. Advanced design features strategically positioned valve pockets, optimized crown geometry, and steel nitride/Napier XX rings for superior durability under severe combustion pressures. The carefully profiled skirt reduces friction while resisting extreme loads—essential for heavily boosted and nitrous-assisted K-series engines demanding maximum structural integrity and reliability.
