JE designs are specifically engineered for extreme applications up to and including professional competition. In this environment, the higher compression ratios, high boost or heavy nitrous use necessitate the higher tensile strength of 4032 and 2618 aluminium 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.
The Dome/Dish require no deburring or preparation and feature a smooth flowing radii for excellent flame travel.
4032 Aluminium Alloy
Pistons manufactured from 4032 wrought aluminium alloy are designed for high performance applications where a strong and quiet piston is required. These pistons require less initial piston to cylinder wall clearance and are quieter at start-up. Ideal for street/road use
