EZ-Street EFI – Electronic Fuel Injection System for V8 Engines
EZ-Street EFI is a complete electronic fuel injection system designed to convert carbureted V8 engines to modern EFI technology with minimal effort. The throttle body mounts directly to any standard 4150-style intake manifold while maintaining the classic appearance by using a traditional round air cleaner.
Its self-learning closed-loop fuel control automatically optimizes the air/fuel ratio for improved performance, drivability, and fuel efficiency. Built-in Bluetooth and the E-Tuner app for iOS and Android allow you to monitor engine data, adjust settings, and fine-tune the system directly from your smartphone or tablet.
