Upon our professional electronic engineers' carefully designing,a new type of CDI has come out.The starting speed is faster than the original design.The ignition angle is precise at the medium and hign speed,which improves the engine's power and saves more fuel.This kind of CDI applies to the improved racing motorcycle and high-speed pursuer. The ignition we product use digital circuits, it controled by single chip precision, The ignition time accurate to 0.1 °, spark energy intensity, easy start, smooth acceleration, not limited to speed, it can to meet the driver at different speeds on the engine power demand. It has the same shell and plug as the original car .
