Wiseco Acura 4v DOME +2cc STRUTTED 84.0MM Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for demanding performance applications. The 84.00 mm bore size is a common upgrade for Honda B16A engines, offering a slight increase over stock to potentially improve displacement and power. The dome features a +2cc volume and a strutted design, which Wiseco engineers use to add strength and manage combustion pressures in high-stress builds.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves and anti-detonation features to ensure a solid seal and prevent premature detonation. They also include an ArmorGlide skirt coating. This coating helps reduce friction between the piston and cylinder wall, which can lead to quieter operation, less wear, and potentially improved efficiency under load. The forced pin oiling design ensures the wrist pin receives adequate lubrication, a critical factor in high-performance engines.

This set includes four pistons, designed for a 30.00 mm compression height and utilizing a 0.827 inch pin diameter. While these pistons are built for serious performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
