PerTronix MR-LS1 Details

For over thirty years, the Ignitor has proven itself in applications ranging from race cars to tractors. 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

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!"
