The MSD Ignition HEI Module is designed to enhance the performance of stock HEI distributors equipped with a 4-pin module. This module is a direct plug-in replacement that delivers up to 8.5 Ampere of current, ensuring reliable ignition even at high RPMs, reaching up to 9000 RPM. Its precision in energy delivery results in improved ignition timing accuracy, which is crucial for optimal engine performance.
