Edelbrock EZ-Street EFI Fuel Injection Kit | 4150 Flange | Up to 650 HP SKU: 6770

Edelbrock EZ-Street EFI Fuel Injection Kit | 4150 Flange | Up to 650 HP

Upgrade your carbureted V8 with modern fuel injection using the Edelbrock EZ-Street EFI system. Designed as an affordable, user-friendly solution, this throttle body EFI kit delivers improved drivability, easier starting, and better fuel control—all while maintaining a classic carburetor-style appearance.

Important: This system requires a 4-barrel intake manifold with a standard 4150-style flange. It is designed to replace a 4-barrel carburetor and will not directly fit a 2-barrel intake without an adapter.

For best results, we recommend pairing it with an Edelbrock Performer 4-barrel intake manifold, which offers excellent street performance and a clean, direct-fit installation.
