Upgrade your classic Chevrolet to a Pertronix Ignitor fits in 20 minutes, under the cap no one will know.

For better performance upgrade to a Pertronix Coil

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.


Operating Voltage: 8-V to 16-V DC

Temperature Range: -50 to 300F

RPM Range: 0 to 15,000 RPM

Can be used with most point-type coils, optimal performance achieved when used with our Flame-Thrower® 40,000 volt coil.

Works great in stock point-type distributors as a trigger for multi-spark CD ignitions, eliminating the need for expensive aftermarket distributors.

No complicated wiring makes installation easy.

A solid-state electronic ignition system. "Never change points again!"
