Overview

Engine Works MegaFire 4-Pin HEI Performance Modules

Engine Works MegaFire 4-pin HEI performance modules are engineered to optimize ignition system performance in GM 4-pin HEI applications through advanced solid-state circuitry, precision dwell control, and current-limiting protection. Designed to increase coil saturation and maximize secondary voltage output, these modules deliver higher spark energy for improved combustion efficiency, enhanced throttle response, and stable ignition timing under high-RPM and high-load operating conditions. Integrated thermal management and coil-current control circuitry help prevent module and coil overheating while maintaining consistent spark output across the engine's operating range. As direct-fit replacements for factory HEI modules, MegaFire performance modules provide the reliability, electrical stability, and ignition performance required for street performance, towing, marine, and racing applications.
