Description
Product Overview
The Pertronix Electronic Ignition Conversion Kit (Model 1665A) is a precision‑engineered replacement for traditional mechanical points. Crafted from a machined exterior and epoxy‑molded housing, the unit resists oil, dirt, grease and moisture, delivering a maintenance‑free solution. Weighing just 3.2 ounces and measuring 6.2 x 4.8 x 1.6 inches, it fits a wide range of gasoline engines. The kit utilizes cobalt magnets and a Hall Effect circuit, eliminating moving parts and providing a stable, adjustment‑free timing with a 2:1 improvement over conventional systems. Its double‑voltage output increases coil output, resulting in stronger sparks, higher horsepower, and better fuel economy.
Usage
Designed for both DIY hobbyists and professional technicians, this conversion kit is ideal for classic car restorations, performance upgrades, and everyday commuter vehicles. Install the ignitor in place of the factory points to instantly gain a more reliable ignition system that performs in harsh environments—whether on dusty backroads, humid coastal climates, or high‑temperature racing tracks. The kit’s universal fit makes it suitable for a broad range of makes and models, delivering consistent results for street driving, weekend track days, and off‑road adventures.

FAQ
Will this kit fit my specific vehicle model?
The Pertronix 1665A kit is designed to be a universal replacement for most gasoline engines that use traditional points. Verify the spark plug thread and coil compatibility, but in most cases it will bolt directly into the existing mounting location.
Do I need any special tools to install the conversion kit?
Installation requires basic hand tools such as a screwdriver, socket set, and possibly a timing light for verification. No specialized equipment or welding is necessary.
How does the Hall Effect sensor improve ignition performance?
The Hall Effect sensor detects the rotor position without physical contact, eliminating wear and providing precise, consistent timing. This results in a more reliable spark and better overall engine efficiency.
Is the kit maintenance‑free?
Yes. The epoxy‑molded housing protects internal components from contaminants, and the solid‑state design has no moving parts that require adjustment or replacement.
What warranty does Pertronix offer on this product?
Pertronix provides a limited one‑year warranty covering defects in materials and workmanship. Registration on the Pertronix website may extend warranty coverage.
