PerTronix 9HO-181 Details

The Ignitor II provides increased starting voltage with adaptive dwell control. Ignitor Module Kits are extremely easy to install and fit into your original distributor to maintain your stock look. No additional ignition box is required keeping a clean look under the hood.

Ignitors are available for most distributors that came with mechanical breaker points and will cover AUTOMOTIVE, MARINE, INDUSTRIAL and AGRICULTURE applications

For the specified Holley eight-cylinder ignition-conversion application.
Adaptive dwell control is a key feature of the Ignitor II electronic module.
Designed to provide increased starting voltage.
Fits inside the specified original distributor to maintain a stock-looking engine bay.
Electronic ignition conversion replaces mechanical breaker-point operation.
Self-contained design requires no additional ignition box.
Designed for straightforward installation in the matching distributor.
