FAQ

Q: How do I confirm this piston will fit my Mitsubishi K3E/K4E engine?
A: The most reliable method is to match the part number. Locate the part number (30A17-00050) on your original piston or in your engine’s official service manual. Cross-reference this with our listed part number. The engine model and serial number plate on the block can also be used for verification.

Q: Is this piston sold as a single unit or in a set?
A> This listing is for a single piston. For a complete engine overhaul, you will need to purchase a quantity matching the number of cylinders in your engine (e.g., 4 for a 4-cylinder K3E). Please order the required quantity. Piston rings and wrist pins are typically sold separately.

Q: What precautions should be taken during installation?
A> Professional installation is recommended. Key steps include: ensuring the cylinder liner/block is within specification, properly fitting new piston rings with correct end-gap, using assembly lubricant, and carefully installing the piston with a ring compressor to avoid damage. Always follow the engine manufacturer’s torque specifications and procedures for connecting rod bolts.
