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 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 ...

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 ...

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 ...

How does spark plug timing work? An explanation of automotive ignition systems. Ignition coils, distributors, and firing intervals all play an important role in ignition. Note: The cylinder order from ...

"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 ...

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 ...

Why Ford built a bigger distributor cap. Discover the engineering reason behind this unusual ignition design. #Ford ...

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, ...

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 ...
