Description

PerTronix Ignitor lobe sensor solid-state ignition systems replace breaker points and troublesome factory units with a dependable, self-contained, and maintenance-free electronic ignition system. The Ignitor has been called the "stealth" ignition because of its quick installation and nearly undetectable presence under your distributor cap. There is no "black box" to clutter the engine compartment. PerTronix Ignitor has proven itself in applications ranging from race cars to tractors. Order the model recommended for your vehicle, engine, and distributor application.

Product features:

* Delivers twice the voltage to your spark plugs—increasing horsepower, fuel economy, and spark plug life
* 2:1 improvement over "points" in current fall time for increased coil output
* No points to burn or moving parts to wear out
* No magnetic sleeve or ring needed; uses existing distributor lobe for sensor trigger
* Epoxy molding makes the module impervious to dirt, oil, grease, and moisture
* Stable timing—no need for any adjustments
* Will trigger most multi-spark CD ignitions
* Available for 6 and 12 V negative and positive ground systems
