Description

The Pertronix Ignitor Kit is an electronic ignition conversion for original Marelli distributors.

This kit delivers twice the voltage to spark plugs for increased horsepower, fuel economy, and spark plug life. It offers a 2:1 improvement over points in current fall time for increased coil output.
