Engine Piston – Kia (23041-2E803)

Engine Piston is a reciprocating component that seals the combustion chamber. Clearance and surface finish decide whether it seals correctly, so the bore has to be measured before a replacement is chosen.

Replace the Engine Piston when a leak-down test shows air escaping past the rings, when the skirt is scuffed, or when ring lands are cracked. Check the ring end gap in the bore it will run in.

The Engine Piston in this listing carries part number 23041-2E803 and sits in the Pistons, Rings & Cylinders category. The number stamped on the original part is the only reliable cross-reference.

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here is genuine KIA, and this Engine Piston keeps the original engineering number, which matters once a number has been superseded more than once.
