Description

These 2618 forged pistons have an 87.50mm bore, designed for a 91.0mm stroke with a 139mm rod. The 32.3mm compression height and 21mm pin diameter ensure a seamless fit. A -9.2cc dish helps achieve a 12.5:1 compression ratio. Mahle MS Series pistons feature Phosphate, Grafal, Hard Anodized top ring groove, and TBC (Thermal Barrier Coating) for reduced friction, increased efficiency, and greater heat dissipation.
