With tighter emission regulations being enforced on vehicle manufacturers it leads to the creation of engines that operate on lower fuel consumptions. This results in the ignition coil having a greater spark output to ignite these leaner fuel mixtures.

Whether it is an integrated ignition coil inside a distributor which supplies the output spark for all cylinders, a coil pack or an individual per cylinder configuration coil over plug, they all have to ignite the air - fuel mixture efficiently so vehicle drivability and emissions aren’t compromised. Only the highest quality ignition coil can perform this function without failing prematurely.
