Piston – Ford (4c4z4211ac)

Piston contains combustion in the cylinder bore and transfers force to the connecting rod. It is matched by bore diameter and ring groove width rather than by model year alone.

Replace the Piston when compression is low on one cylinder, when oil consumption climbs without an external leak, or when a teardown shows scoring in the bore. Measure the bore before ordering: standard size will not seal a cylinder that needs honing.

For this Piston the reference is 4c4z4211ac, in our Pistons, Rings & Cylinders range. Compare it with the number on the part you are replacing rather than with a photograph.

Genuine FORD part for the Piston. Where the manufacturer has superseded a number, the current reference is the one that ships.
