Pertronix Ignitor electronic ignition. For over thirty years, the Ignitor has proven itself in applications ranging from classic cars to race applications. The Ignitor replaces breaker point and troublesome factory electronic ignitions 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. Features: delivers twice the voltage to the spark plugs, increasing horsepower, fuel economy, and spark plug life.
