Points Box 12amp Pro Mag

The MSD Points Box 12amp Pro Mag is an electronic ignition control module designed for high-performance ignition systems that demand reliability and precision timing. This black-finished unit replaces conventional mechanical points with solid-state electronic switching, eliminating the maintenance issues and inconsistent spark delivery associated with traditional contact breaker systems. Built for enthusiasts and professionals who run MSD Pro Mag ignition systems, the 12amp Pro Mag delivers the stable, repeatable ignition curve needed for street and racing applications where engine performance depends on accurate spark control.

The Points Box 12amp Pro Mag operates as a dedicated power module within MSD's Pro Mag system, managing the 12-amp output to the ignition coil with electronic precision that mechanical points cannot achieve. Electronic control removes point bounce, arcing, and wear—problems that degrade spark quality over time and miles. The compact housing measures 7.5 x 4.9 x 10.1 inches and weighs 4.55 lbs, engineered for engine bay mounting where it resists vibration and temperature fluctuations common in high-output engine environments. This solid-state design ensures consistent dwell time and spark advance, translating directly to improved cold starts, smoother idle quality, and optimized combustion across the RPM band.

Installers and engine builders working with complete MSD Pro Mag ignition packages will find the 12amp Pro Mag essential for systems requiring higher current delivery and extended dwell capability. This module integrates seamlessly into MSD's Pro Mag ecosystem, pairing with compatible distributors, coils, and control boxes to deliver race-proven ignition architecture. Mounting is straightforward for anyone with basic automotive electrical experience, and the rugged construction handles demanding street and strip duty. Whether tuning a carburetor engine, classic muscle car, or competition platform, the Points Box 12amp Pro Mag provides the electronic foundation that transforms ignition system performance from adequate to competitive.
