There is a 2013 NV1500 ignition coil connected to each of your spark plugs, and it's responsible for increasing the voltage in electrical current before so it can be used by the plugs. Signs that your coils may be going bad include lowered MPG, lessened acceleration, trouble starting, and a lit Check Engine Light. We carry a variety of 2013 Nissan NV1500 ignition coils from trusted brands, so you can select the ones that meet your needs.
