Set of Six JE 80mm (3.150") Bore, Dome Piston for Porsche Air-Cooled 2.0L

JE designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 4032 & 2618 aluminum alloy, which has been optimized for aftermarket Nikasil cylinders. The JE Piston Porsche series now include low friction skirt coatings and are lighter than before, improving both performance and longevity.

Dome/Dish requires no deburring or preparation and feature smooth flowing radii for excellent flame travel.
