Spark plugs have a pretty predictable life cycle, but ignition coils can be harder to track. Here's how to tell if an ignition coil is on its way out.

MSD has a whole series of Blaster 2 and 3 cannister-type ignition coils that can replace stock coils used in various OE ignition systems. They're also a good complement for MSD 6-series ignitions.

Most people think you can check a small engine’s ignition system by removing the spark plug and grounding it while cranking the engine and watching for a spark. Nope. That just confirms that the spark ...

MSD's new Digital Coil-Per-Cylinder (CPC) ignition system offers state-of-the-art control over all ignition-related operations. The components required include two control boxes (system and ...

Condensers and coils can last many years; points were the main problem. They had to open and close each time a cylinder fired. At a 3,000-rpm cruising speed that’s 12,000 times a minute for a V ...

The '84 turbo V6 Regals and Rivieras have a distributor less ignition system, the first production car to do so. There'll also be an adjustable high-output off-road setup based on the '83 dual ...

Individual ignition coils, typically mounted directly atop each spark plug, minimize the chance for spark loss. They do occasionally fail, usually due to cracks or porosity in the coil’s plastic ...

This type of ignition system with a separate ignition coil -- a rotor in a distributor that sends electrical current to each spark plug through wires in the cap -- began to phase out in the 1970s.

The coil in an electronic ignition system creates a more powerful spark in the 70,000- to 80,000-volt range. That allows for a larger spark-plug gap, translating into more efficient combustion.

The system developed by Transient Plasma Systems (TPS) of Torrance, Calif. substitutes low-temperature plasma for the traditional spark and also does away with ignition coils.

Originally the lawnmower engine used a magneto coil ignition system, magnetos are simple and very common in lawnmowers. The magneto is designed to produce a high voltage spike when influenced by a ...
