EJ205 Impreza WRX 79mm stroke 2002-2005 (FSR technology)
Machined from 2618 T6 high tensile forged aluminium these pistons feature smooth flowing radii and are supplied ready to fit. All JE pistons are specifically engineered for extreme applications.
These pistons feature FSR asymmetrical forging, a state of the art asymmetrical skirt technology which reduces both friction and mass whilst providing a more rigid and durable platform. Thanks to this the pistons are able to operate under higher boost levels or heavy nitrous usage.
All FSR pistons include offset pins, for quiet operation and a new smooth finish crown process for improved flame travel.
Piston rings and straight carbon wall gudgeon pins are included with the pistons.
For use with a 79mm stroke crankshaft.
