The higher voltage and hotter spark help ignite leaner fuel mixtures used in lower emissions engines. Distributorless ignition system components DIS ignition systems use one ignition coil for every two cylinders. The ignition coil may be designed as a separate unit, called a coil pack or may be … Read More
