The PerTronix Ignitor II replaces the mechanical breaker points inside an original single-point Autolite-Prestolite 8-cylinder distributor with a solid-state Hall Effect trigger, keeping the stock distributor housing intact for marine, industrial, and agricultural applications.

PerTronix 91581LS Features:

• Fits original 8-cylinder single-point Autolite-Prestolite marine distributors.
• Adaptive dwell control maintains peak spark energy across the entire RPM range.
• Develops up to 4 times more available energy between 3000 and 5000 RPM and 2 times more plug voltage than stock points.
• Hall Effect lobe sensor trigger compensates for electronic delay by adjusting spark timing throughout the RPM range.
• Ring terminal connections simplify wiring to the factory harness.
• Legal in all 50 states and Canada under CARB EO D-57-22.
