It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

If there is a standard in the world for a stand-alone electronic ignition distributor for GM engines, it has to be the High Energy Ignition or HEI distributor. This large cap distributor first ...

How can you say "no" to simplicity, reliability, and an increase in power? Yeah, neither could we. Our old '75 Dodge workhorse with a 440ci engine (the Lawg) was still running the factory ignition ...

The ignition system is a glutton for punishment. As the miles rack up, the distributor wears out, the coil gets abused, and the spark plug wires melt. The steadfast ignition system only gets attention ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...

Q. I've noticed my new car doesn't have a distributor or spark plug wires, unlike every other car or truck I've ever owned. Can you explain how this works? A. This is one of the neatest automotive ...

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 vehicles with distributor-type ignition systems use ignition (or spark plug) wires to send electrical current from the distributor to individual spark plugs, with the timing based on their ...

This animated film "Spark In The Firing Line" provides an in-depth look at the ignition system of modern motor vehicles, focusing on the role of spark plugs in igniting fuel within the combustion ...

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, ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...
