FAQ

Q1: How do I confirm this piston kit will fit my specific S4E engine?
A1: For guaranteed fitment, please provide the full engine model number, serial number, and if possible, the OEM part number stamped on the original piston. Our technical team can cross-reference this data to confirm compatibility before you order.

Q2: Is this piston kit sold individually or as a set for all cylinders?
A2> This listing is typically for a single piston kit (one piston, pin, and locks). For a complete engine overhaul, you would need to order a quantity matching the number of cylinders (e.g., 4 kits for a 4-cylinder engine). Bulk pricing is available for full sets.

Q3: What are the recommended installation procedures for this aftermarket piston?
A3> Professional installation is crucial. Always follow the engine manufacturer’s service manual for clearance checks, ring gap setting, pin installation, and proper cylinder honing. We recommend replacing piston rings and inspecting the connecting rod and cylinder liner simultaneously for optimal rebuild results.
