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 ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

If you have a classic, vintage, or otherwise old car, you've probably heard of the distributor that it features. It's part of the ignition system that transfers current from the battery to the ...

When we first met Steve Davis, owner of Performance Distributors, we knew immediately that he was an out-of-the-box thinker. That's a pretty common characteristic among successful entrepreneurs, but ...

Distributors used to be a fixture on car engines, but they were replaced by coil packs somewhere in the 1980s. Here's why automakers switched.

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 ...

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 ...

"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 ...

The ignition (or distributor) cap is where ignition wires that run to the spark plugs receive high-voltage current from the ignition coil. Metal contacts in the cap connect with contacts in the ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

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 ...
