Custom Ignitor Electronic Ignition Kit (LU-146LSP12) by PerTronix. For over forty years, the Ignitor has proven itself in applications ranging from race cars to tractors. The Ignitor replaces breaker points 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. There is no "black-box" to clutter the engine compartment. For optimal performance, use the Ignitor with Flame-Thrower 40,000 volt coils.
