One of the contributing factors to the LS engine's success when it comes to performance and economy can be traced to its DIS (distributorless ignition system). By assigning an individual coil for ...

A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

Have you ever wondered why GM, Ford, and Chrysler converted from distributors to distributorless ignition systems (DIS)? Sure, they eliminated the whirling mechanical device that spins a rotor that ...

When Ford introduced the SEFI 5.0L High Output Mustang in 1986 many predicted the end of the tunable engine. Ironically it was the beginning of a new era of super-tunable small-block Fords that would ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

The spark plug was a key invention in the history of the internal combustion engine, allowing combustion to be easily controlled and engines to rev faster than messy earlier designs. Mid-century cars ...

Sudden misfires feel like the engine just lost its rhythm, yet the real drama often starts inside a failing coil pack. When ignition coils break down under heat, vibration, or age, they can turn a ...

Does your Ford small-block need a potent ignition system? Performance Distributors Street/Strip DUI is an easy upgrade for a ...

Engines need spark plugs to burn their air/fuel mixture, and the spark plugs need a jolt of electricity to do their work. Older cars with conventional distributor-based ignition systems did it by ...

One of the main differences in regular maintenance between a gasoline and a diesel-powered car is replacing the spark plugs. While diesel engines rely on compression to create ignition, and thus ...

The forefathers of speed could only dream of street cars that were both reliable and capable of 800 hp or more—funny thing is, these days it is commonplace. We can thank technology’s rapid advance ...
