COIL ON BOOT PLUG

ALL ABOUT COIL ON BOOT PLUG

As ignition wire sets are no longer used on new cars and trucks, coil-on-plug (direct ignition) technology is taking their place and becoming an important part of the new ignition systems. This product category is growing and will be at the forefront in the years to come. Direct ignition (DI) systems utilize a coil boot and spring assembly to deliver the secondary voltage to the spark plug from the ignition coil. The boots should be replaced any time the spark plugs or coils are serviced or if they become contaminated with water, oil, or coolant.

Coil boot plugs are becoming the standard in newer vehicles, replacing the old coil and spark plug wire system. With a coil boot, or coil-on boot plug, each spark plug has its own ignition coil, rather than a series of coils that are all fed through one cable and then dispersed through a distributor cap. As long as your vehicle is already converted, or came with a system that uses these kinds of plugs, the process to put on a coil boot plug is easy.
