HEI Module - Street Fire Distributor

The MSD IGNITION HEI Module Street Fire Distributor (part number 5596) is an ignition control module engineered for high-performance street applications using HEI distributor platforms. This compact module weighs just 0.17 lbs and integrates seamlessly into existing HEI-based ignition systems, delivering precise spark timing control for optimized combustion and engine responsiveness across a wide range of operating conditions.

MSD Ignition modules are known for their durability in automotive performance environments where reliable spark generation is critical. The Street Fire series targets enthusiasts and builders who require dependable ignition module performance without exotic complexity. Installation into an HEI distributor housing is straightforward, making this module a practical choice for carburetor-fed engines and early fuel-injected platforms that retain original HEI distributor architecture. The compact dimensions (6 x 1.5 x 7.85 inches) ensure fitment within standard under-hood packaging constraints.

This module is suited for street-driven vehicles, weekend track cars, and engine rebuilds where HEI distributor compatibility is a requirement. Owners of classic muscle cars, first-generation muscle trucks, and 1970s–1980s domestic performance platforms commonly rely on HEI-based ignition systems. The MSD 5596 provides a straightforward upgrade path for improving spark consistency without requiring a complete ignition system overhaul. It serves as both a replacement component and a performance refresh for existing HEI setups.
