PerTronix Ignitor® Solid-State Ignition Systems

PerTronix Ignitor® solid-state ignition systems deliver more energy with greater timing accuracy. The secret lies in the trigger magnets, which spin with the rotor and operate a switching module that requires no external control box. These systems are immune to heat, oil, and debris—and install in about 15 minutes with only two wires to connect. They come with a switching module, hardware, and instructions. Ignitor® is an ideal choice for collector car restoration because it fits entirely under the distributor cap.

MSD Iron Distributor Gears

MSD puts their years of experience to work in making these top-notch iron distributor gears. Their high grade, ductile iron is micro polished for a smooth and scuff-free finish then Melonite QPC coated to reduce friction and initial wear. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these oversized gears for tighter mesh between the camshaft and distributor drive gears.
