Quick facts
- Part: Sealed H1123CP .50MM engine piston
- Fits: 2001-2010 Ford Explorer V6 4.0L and other vehicles
- Material: Hypereutectic
- Condition: New
Oil burning, blow-by or an engine knock can point to worn pistons, rings or cylinder walls. If the pistons are the cause, this set replaces them. With the engine off and cool, oil on the spark plug tips is a first thing to look for, and a shop can sort out the cause with compression and leak-down tests.
