Our 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 max 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. Our reinforced bobbins prevent voltage flashover for an extended service life. As a tier I manufacturer with engineering and design capabilities second to none, our ignition coils are made to the highest quality standards.
