Unlike older vehicles, which needed ignition tune-ups at least once a year, most vehicles on the road today have electronic ignition systems that are built to go for years without the need for them.

State-of-the-art electronic ignition systems can perform more reliably than old-fashioned breaker points systems, supplying the increased spark necessary to reliably fire today's modified engines.

With electronic ignition, the reluctor, mag pick-up and ECU (not shown) collectively serve the same purpose as contact points. The magnetically conductive reluctor is the electronic equivalent of the ...

Back in the day, point-triggered ignition system tune-ups were routine and happened roughly every 12,000 miles, along with a set of spark plugs and an ignition timing adjustment. These days, we’re so ...
