• Verified fitment: these Applications: 2008-2015 Mitsubishi Lancer Evolution X
• 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 2618 aluminum alloy. - Dome/Dish requires no deburring or preparation - 2618 T6 high tensile forged aluminum - NEW ASYMMETRICAL FSR forging! State of the art asymmetrical skirt technology reduces friction and mass while providing a more rigid and durable platform (Skirt Style F). - FSR pistons include offset pins for quiet operation. - Dished pistons feature new Smooth Finished Crown process for excellent flame travel.
• Note: Bore sizes 86.5mm, 87mm, 89mm, and 90mm are made to order and will have longer lead times
