id0110b3100600

• The piston head has a concave recess to accommodate the turbocharger.
• A superior quality, heat resistant, highly-conductive aluminum alloy has been adopted for the pistons.
• Offset pistons have been adopted to reduce piston slapping.
• The piston has an arrow mark, located on top of the piston, pointing to the front side in order to prevent improper installation.
• A bushing is installed on the small end of the connecting rod for a full-floating connection of the piston, piston pin, and connecting rod.
• The construction of the piston skirt is asymmetric on the left and right side to prevent interference between the piston and oil jet.
