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:

These year Ford Lincoln Mercury vehicles use individual ignition coils that sit over the spark plug. They are commonly referred to as "coil on plug, coil packs, or COPS. An ignition coil is a crucial part of your ignition system. 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. If you have a 98-04 Navigator, make sure it is DOHC (double oevrhead camshaft). The SOHC uses a different style of ignition coil.

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 DG512 style ignition coil is a commonly replaced item in most of the Ford cars, trucks and SUV. In some instances of minor misfiring on Ford Lincoln or Mercury vehicles, the check engine light will not illuminate. This is because the PCM does not illuminate a check engine light unless the misfire is more than 2.3% of the firing time. It does howeverstill record the misfire. We can help you find these for FREE in our how-to section.

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