MSD 5591 Street Fire EFI Distributor GM V8 1988-1995 External Coil

The MSD 5591 Street Fire EFI Distributor is a direct drop-in stock replacement distributor engineered for 1988–1995 GM EFI V8 engines equipped with an external coil. Part of MSD's Street Fire line — a value-focused branch of MSD designed to deliver maximum performance per dollar — this distributor is spec'd by MSD engineers to provide reliable ignition performance without breaking the bank.

This distributor features a cast aluminum housing that is stronger than standard OEM units, along with a factory-style ignition module, a new distributor cap, and rotor included right out of the box. The maintenance-free magnetic pickup trigger provides accurate, consistent spark signals, while the computer-controlled (EST) advance integrates seamlessly with the factory ECM — no external ignition box required. The HEI-style terminal cap and melonized distributor gear round out a package that installs easily and performs reliably.
