Wiseco K20/24 87.5mm Bore Pistons at 11.1:1 compression ratio are engineered for aggressive forced induction and high-boost applications. This complete four-piston kit includes wrist pins, locks, and rings for ready-to-install convenience. Manufactured from proprietary forgings, these pistons offer exceptional strength-to-weight ratio critical for elevated boost levels. Advanced engineering includes precision valve pocket design, optimized dome architecture, and steel nitride/Napier XX ring technology for superior heat resistance and longevity. The carefully profiled skirt minimizes friction while withstanding extreme combustion pressures—essential for reliable performance in turbocharged and supercharged K-series builds.
