This is brand new ignition coil from the HIGHRS brand, which has higher ignition energy than ordinary ignition coils, smoother acceleration, more linear power, eliminates idle shaking, and solves jerking problems. Plug and play, non-destructive installation. After installing the HIGHRS ignition coil, please connect the diagnostic computer and clear the fault code. This operation can allow the onboard ECU to re match the ignition coil data, resulting in better coordination between the engine and ignition coil, more perfect results, and more stable and durable.
