Ignition coil packs for vehicles branded as Mopar are manufactured by various suppliers. These suppliers can change over time and may differ depending on the specific engine application. Original Equipment Manufacturer (OEM) parts are those produced by the company contracted by the vehicle manufacturer, while aftermarket parts are produced by other companies. Understanding this distinction is crucial for consumers seeking replacement components. For example, a coil pack for a 5.7L Hemi engine might be produced by a different supplier than one for a 3.6L Pentastar engine, even if both vehicles carry the Mopar brand.
Reliable ignition coils are essential for proper engine function. They transform the battery’s low voltage into the high voltage required to create a spark across the spark plugs, igniting the air-fuel mixture within the cylinders. A failing ignition coil can lead to misfires, reduced power, decreased fuel efficiency, and increased emissions. Over the years, ignition coil technology has evolved from single coils serving multiple cylinders to individual coil-on-plug systems offering greater precision and control. This evolution has led to improvements in engine performance, reliability, and emissions control.
