    PerTronix 40501 Details

    The hotter the spark, the easier your engine will start, and this 40,000 volt coil is just the ticket to a quick start! Its higher voltage allows larger spark plug gaps for added power, smoother response and better fuel economy. These coils are internally resisted so they are compatible with many inductive ignition systems.

    • 40,000 volts
    • Smooth Chrome finish
    • For use with 12 volt inductive ignition systems
    • 3.0 Ohm primary resistance.(common for 12V 4,6 cyl)
    • Legal in all 50 states and Canada
