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 ...

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, ...

Every gasoline engine is basically a series of controlled explosions, and the coil pack is the component that lights the fuse. Your car's battery puts out a measly 12 volts, which is great for your ...

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 ...

Ignition coils last far longer than spark plugs and only need replacement when symptoms appear. Here’s how to tell if coils ...

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 ...

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 ...

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 ...

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 ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...
