Piston – Kia (23041-2E843)

Piston is one of the pistons that converts combustion pressure into motion. Ring land dimensions and skirt coating are specific to the build, not to the displacement.

Replace the Piston during any rebuild that has the head off, and always when the bore shows vertical scoring. Piston-to-wall clearance is set by measurement, not by the part number alone.

Reference number for the Piston: 23041-2E843. It is filed under Pistons, Rings & Cylinders, and it is the number that has to match the part coming off the vehicle.

The stock here is genuine KIA, and this Piston keeps the original engineering number, which matters once a number has been superseded more than once.
