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 ...

Older models of cars used to rely on distributor-based ignition systems. Today, though, modern vehicles rely on coil packs ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong ...

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 ...

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 ...

When it comes to your motorcycle’s electrical and ignition systems, there’s a lot to know about diagnosis and repair. One potential complication involves your bike’s CDI box. But what is a CDI box on ...

I have a 1954 Ford with a 272 Y-block. Before I got it the previous owner had added triple carbs, dual pipes, and a PerTronix point replacement kit. The coil was a standard 12V replacement and there ...

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 ...

Newer engines like as the Coyote, LS, and G3 Hemi have an ignition coil for each cylinder. This modern approach is called "coil near plug" or CNP, and it replaces the distributor with eight small ...

Precise ignition timing is essential for high-performance engine tuning and ensuring your small-block or big-block is delivering every horsepower within its capability. Since the era of poodle skirts, ...

The ignition coil converts the vehicle’s 12 volts to the more than 10,000 volts required to produce an effective spark in the spark plugs, which in turn ignite the air-fuel mixture in an engine’s ...
