|The ignition coil converts a low voltage current to high voltage energy that is delivered to the spark plug to ignite the air fuel mixture within the cylinder. A coil-on-plug is designed to perform the functions of both the ignition coil which creates the spark energy, and the spark plug wire set that is designed to contain and deliver the high voltage energy to the spark plug.
In Coil-on-Plug technology, since each cylinder has a coil, the PCM controls individual cylinder firings for more precise ignition timing, reduced emissions and better fuel economy.
The Coil-on-Plug (COP) coil is usually mounted on the top of the cylinder head just above the spark plug. The coil is connected to the spark plug with a stainless steel spring connector and protective insulating boot.
- Intermotor™ Coil-on-Plug assemblies are manufactured from the finest components for optimum performance and a long service life under all operating conditions
- Neodymium in the core creates the strongest magnetic field and produces maximum high voltage output at all speeds
- High dielectric epoxy is injected into the case and pulled into a vacuum to eliminate air pockets and prevent moisture intrusion or thermal breakdown
- Intermotor’s™ reinforced bobbins prevent voltage flashover for an extended service life
