Engine Piston – Ford (9t4z6108b)

Engine 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 Engine 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.

Ordering reference for the Engine Piston is part number 9t4z6108b, categorised under Pistons, Rings & Cylinders. Match that number against the component you are removing before you order.

This is FORD dealer-sourced stock rather than an equivalent, so the number on the Engine Piston traces straight back to the manufacturer.
