FAQ

Q: How do I confirm this piston will fit my specific Mitsubishi engine?
A: The surest method is to cross-reference the part number. Locate the part number stamped on your original piston (typically 32A17-00100 or 32a1700100) or consult your engine’s service manual for the S4S/S6S model designation.

Q: Is this piston sold as a single unit or as part of a set?
A> This listing is for a single piston. For a full engine overhaul, a complete set matching the number of cylinders in your engine (4 for S4S, 6 for S6S) is recommended to ensure uniform performance.

Q: What other components should I replace when installing this new piston?
A> For optimal engine life and performance, we strongly recommend replacing piston rings, wrist pins, and cylinder liners simultaneously. Always inspect connecting rods and bearings during assembly.
