Description
Set the compression ratio to the stock piston 10.7: 1, Forged high-compression pistons 12.2: By setting it to 1, the power output will be increased with the stock displacement.
The top surface of the piston has been flattened to improve combustion efficiency.
The piston body is cold forged from a special aluminum alloy and precision machined for light weight and high strength.
The piston weight is reduced by 20g compared to the stock piston (casting).(Comparison of a single piston)
0.8 / 0.8 / 1.5 thin piston rings are used to reduce friction loss.
