Austin Coil—drag racing crew chief extraordinaire and a friend for more than 50 years—is a lucid and spry 80 years of age.

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

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 ...

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 ...

"Coil bind" occurs when a spring's coils stack solid at or before full camshaft lift. This develops an infinite load on the valvetrain, causing its weakest link to fail. If you're lucky, the result is ...

Ignition coils play a crucial role in a vehicle's ignition system as essential components that facilitate the engine's combustion process. They are responsible for converting the low voltage supplied ...

Engines need spark plugs to burn their air/fuel mixture, and the spark plugs need a jolt of electricity to do their work. Older cars with conventional distributor-based ignition systems did it by ...
