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 ...

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, ...

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 ...

We may receive a commission on purchases made from links. Is your car misfiring, having trouble starting, or idling rough? Are you wondering if the problem is one of your coil packs? If you're like ...

If drum brakes and flat-tappet camshafts are old-school technology, then springs are quite literally ancient. In some respects the wooden bows and catapults used by medieval knights to bludgeon their ...

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 ...

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 ...

At 7,000 rpm, a spark plug ignites the air/fuel mixture nearly 60 times per second. Any one of those 60 sparks going amiss can at best be mildly annoying, and at worst cost you a race or an engine.

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...
