Edelbrock Pro-Flo 4 EFI System

The Edelbrock Pro-Flo 4 EFI System is a complete electronic fuel injection kit. It replaces a carburetor and intake setup on a classic V8 engine. Pro-Flo 4 is also known as an EFI conversion kit or throttle-body-style fuel injection system. It gives street, cruiser and performance builds modern fuel delivery. The engine is still the focus, and the kit adds the starting, drivability and efficiency benefits of closed-loop electronic control.

Key Features:

• Self-tuning, closed-loop engine management that adjusts fueling to changing conditions
• Programmable ECU with a wiring harness for plug-and-play installation
• Sequential multiport fuel injection for precise fuel delivery to each cylinder
• Intake manifold and fuel injection hardware engineered to work together as a system
• Includes sensors and key electronic components, as documented for each specific part number
• Handheld or software-based tuning options for fine-tuning

Compared with a carburetor, the Pro-Flo 4 system offers better cold starts, smoother idle, improved throttle response and better fuel economy. It also adapts to changes in altitude and temperature. Each variant in the line is built for a specific engine family. Edelbrock has a long history in performance induction and fuel systems, and this system carries that experience into a modern EFI package.
