As stricter emissions regulations are imposed on automakers, this has led to the creation of engines that operate with lower fuel consumption. This results in the pencil coils having a greater spark output to ignite these leaner fuel mixtures.

Whether it's an integrated ignition coil within the distributor, which provides the output spark for all cylinders, a coil set or individual coil pass plugs configured for each cylinder, they all have to ignite the air-fuel mixture efficiently, so vehicle drivability and emissions are 't compromise. Only the highest quality ignition coils can perform this function without premature failure.

Unfortunately, there has been a significant increase in inferior quality ignition coils from ignition coil core suppliers over the past few years. Consumers and even technologists can easily get confused by the quality of the products available in the market. Problems with workshops that install low-quality parts can include safety, expensive repairs, and more importantly, damage to your reputation.
