Wiseco Professional Series Acura 4-Valve 84.0mm +2cc Dome Strutted Piston Kit (K567M84AP)

Wiseco Professional Series forged racing pistons are engineered for high-output Acura 4-valve engine builds where structural integrity and performance are critical. Forged and machined in the USA from 2618 aluminum alloy, these pistons provide the increased tensile strength required for high-boost or high-compression race applications.

This kit features a strutted forging design to maximize rigidity while minimizing reciprocating weight. The 84.0mm pistons include a +2cc dome profile and are finished with Wiseco's ArmorGlide skirt coating to reduce friction, minimize wear, and provide quieter operation. To ensure reliable performance under extreme thermal loads, the pistons incorporate forced pin oiling and precision-machined anti-detonation grooves to protect the ring land area.
