Edelbrock EZ-Street Throttle Body EFI System

Engineered to provide an affordable and user-friendly upgrade for any V8 engine originally equipped with a carburetor, the EZ-Street EFI system seamlessly integrates cutting-edge technology with traditional styling.

The four-barrel throttle body design mounts to any intake manifold with a standard 4150-style flange and accepts a traditional round air cleaner, just like a classic carburetor. Each unit arrives fully preassembled and pressure-tested, complete with integrated injectors, throttle position and manifold sensors, fuel rails, linkage, and a Bosch 4.9 wideband oxygen sensor. It also includes an ECU, a high-quality wiring harness with a simple 4-wire hookup, and detailed installation instructions. EZ-Street features closed-loop, self-learning fuel technology, with a calibration wizard to make initial startup simple; no need for custom tuning or a laptop. The included EZ-Street Bluetooth Tuner App, available for both iOS and Android, allows users to configure the system, adjust settings, and monitor performance through intuitive preprogrammed dashboards. Data logging, fuel control, and dual electric fan management are all accessible directly from a smartphone or tablet.

Beyond fuel delivery, the EZ-Street EFI offers the option of fully programmable ignition control, enabling optimized performance and improved fuel efficiency. When paired with a Pro-Tuner distributor (sold separately), the EZ-Street EFI can deliver fully integrated timing control at the touch of your fingers. With an internal coil driver and compatibility across most HEI distributors, ready-to-run distributors, and CDI boxes, the system eliminates the need for separate ignition modules. Capable of supporting up to 650 horsepower, the EZ-Street EFI system combines advanced annular-fuel-venturi distribution with modern CAN communication protocols to provide reliable, high-performance results in a simplified package.
