PerTronix (71181): Ignitor III with Digital Rev Limiter for Delco 8-Cylinder

Providing ignition box performance without the box, the Ignitor III ignition module from PerTronix offers five times more spark energy than points systems for your Delco eight-cylinder application. The 71181 Ignitor III includes an integrated digital rev limiter with LED feedback for precise RPM setting. The Memory Safe function stores your setting—eliminating unintended changes to the rev limit—while the Adaptive Dwell control maintains peak energy throughout the RPM range, reducing misfires and improving engine performance.

Note: Legal in all 50 states and Canada (CARB E.O. #D-57-22). Not compatible with CD or multispark boxes.

Features
