Wiseco K20/24 87mm Bore Pistons deliver 10.2:1 compression for extreme boost and nitrous oxide applications. Each complete kit supplies four pistons, wrist pins, locks, and rings for straightforward installation. Manufactured from proprietary forgings, these pistons combine reduced weight with the structural robustness required for severe combustion pressures. Engineering includes precision valve pocket design, advanced crown architecture, and steel nitride/Napier XX ring technology for exceptional heat resistance and longevity. The optimized skirt profile minimizes friction while withstanding extreme loads—critical for heavily turbocharged, supercharged, or nitrous-assisted K-series builds demanding uncompromising strength and sustained performance reliability.
