The listing you are viewing is for a complete set of 4 Araparts brand ignition coils. These are also known as Coil on Plugs, or COPs. If your ignition coils are several years old, it is recommended to replace all at the same time for improved performance. New coils are a major factor when it comes to restoring vehicle performance, and gas mileage. We are able to get our prices so low by purchasing several hundred, and even several thousand coils at a time, when your local auto parts store may only purchase 4-10. We are not a drop shipper. We have a physical location in Northern California.

More Information:

An ignition coil (also referred to as coil pack, coil on plug/COP, coil over plug)  is a crucial part of your ignition system. The ignition coil is a miniature power transformer, which converts the 12v in your vehicle electrical system into tens of thousands of volts. This will send the voltage to the spark plug, and ignite the fuel. Ignition coils wear out over time. Over the years, high and low temperatures, humidity, and even bad grounds and electrical problems can cause ignition coils to fail, or not perform at full capacity. This can cause a misfire, also referred to as hiccups or surging. Because the ignition coils wear in the same environment, it is usually best to replace old ignition coils all at the same time, and save money or time on labor. Other causes are washing the engine bay and rain. The Ignition coils in the 2.5L Nissan Sentra and Altima 2.5 of this age are frequently replaced as they age.

Other know electrical problems in these 2.5L Nissan and Infiniti vehicles have caused ignition coils to repeatedly fail. One common problem is the main electrical ground would break, causing the electrical system to use the ignition coils, and the main vehicle computer as a ground, physically melting them. This ground cable goes from the negative terminal on the battery to the transmission. It breaks from corrosion, and engine movement. Bad engine mounts can accelerate damage to this cable. Check this ground, and all other grounds on this vehicle. If it is broken, replace it.

Checking vehicle grounds, wiring, and other components such as the vehicle computer (also referred to as the PCM, ECU, or ECM) for damage can prevent repeated failure of ignition coils and save hundreds, or even thousands of dollars in repairs.
