Wiseco Professional Series Forged Piston Kit - Mazda 3/6 Mazdaspeed 2006-2013 -13.3cc 9.5:1 (K640M88)

Fits 2006-2013 Mazda 3 Mazdaspeed and Mazda 6 Mazdaspeed models.

Wiseco Professional Series forged racing pistons are engineered for the high-cylinder pressures of serious competition builds. Machined in the USA from 2618 aluminum alloy, these pistons provide the increased tensile strength required for heavy to severe duty turbo applications. Each piston features a dished crown with a -13.3cc volume to maintain a 9.5:1 compression ratio, providing a robust foundation for increased boost levels.

This shelf stock kit incorporates Wiseco’s proprietary ArmorGlide skirt coating to reduce friction, minimize noise, and provide superior seizure resistance. The fully machined crowns include anti-detonation grooves and precision ring grooves to ensure a superior seal under load. Forged-in oiling features, including forced pin oiling, provide critical lubrication to the wrist pin to prevent galling during high-RPM operation.
