While many drivers will be changing their spark plugs more often than ignition coils, some might wonder if both should be ...

Paging through an ignition catalog reveals all sorts of different ignition coils for conventional distributor-type ignition systems. To say it's a mite confusing is an understatement!Just how does an ...

[Teodor] writes in with a unique Tesla coil he designed and built. Unlike most Tesla coils, [Teodor]’s design is able to run with a fairly low input voltage because it doesn’t use a static spark gap ...

You've got an intake, an exhaust, and a programmer but are still hungry for more bolt-on performance. Most people turn attention to the ignition next. To get more ...

As long as the internal combustion engine has existed, engineers have been trying to find better ways of igniting the highly combustable mixture of air and gasoline that powers cars. Everything from ...

High-voltage experimenters are a unique breed. They’re particularly adept at scrounging for parts in all kinds of places, and identifying how to put all manner of components to use in the service of ...

For most of us at least, when it comes to ignition systems, as long as we are getting spark in all eight cylinders and the engine isn't popping and missing, we're usually pretty happy. Maybe we'll ...

It wasn't all that long ago that GM engineers designed the original HEI system to replace the decades old points-type ignitions. In the mid-'70s, leaner mixtures demanded greater voltage and more ...
