IMPROVED
FUEL ECONOMY

PF4 EFI has the potential for improved fuel economy when upgrading from a carburetor.

EZ-STREET® EFI SYSTEMS


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-Flo 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.

    FEATURES INCLUDE:
  • New Kit starting at $1297.95
  • Designed with standard 4150-style flange
  • Comes preassembled and pressure-tested
  • Self-learning fuel technology
  • Capable of supporting up to 650 Horsepower

EFI Fuel Systems and Components

FUEL SYSTEM KITS & COMPONENTS


Browse through several EFI Fuel Systems, components andreplacement parts, to ensure your Edelbrock EFI System is always running top Notch. These Universal SumpFuel Kits are designed to provide the necessary high fuel pressure required for EFI applications in vehicles equipped with an existing low pressure carbureted fuel system.

    FEATURES INCLUDE:
  • Complete self-contained system- Easy to install
  • Delivers constant fuel pressure with no fuel return line, external fuel pressure regulator or fuel tank modifications necessary
  • Compatible with existing factory fuel tank and pump



THROTTLE BODIES


Edelbrock throttle bodies are available in several sizes to deliver increased performance for a wide variety of applications. Smaller sizes are slightly larger than stock and are a great first step for stock or mildly modified engines. Larger sizes are for more radical, high-output engine combos and in most cases, require port matching of the manifold for proper fitment and performance.

    FEATURES INCLUDE:
  • Throttle blades are staked to the shaft for secure fit and finish
  • Throttle shafts ride on sealed bearings for efficiency
  • New Throttle position sensor installed on most apps
  • Castings are machined and assembled in the USA



Performance Throttle Bodies
Performance Intake Elbows

INTAKE ELBOWS


Edelbrock Throttle Body Elbows are the best way to adapt LS1, LS2 and Ford 5.0L-based throttle bodies to EFI manifolds with traditional square-bore mounting pads. An internal divider optimizes flow quantity and distribution into the manifold and they can be mounted forward, backward, or sideways on Victor EFI square-bore manifolds.

    FEATURES INCLUDE:
  • 3 versions allow tuners to position the throttle body low for hood clearance or higher for maximum airflow
  • Available in satin or black powder coated finish
  • Elbows include a universal throttle cable bracket

EXCLUSIVE E-TUNER 4 APP


Pro-Flo 4 Electronic Fuel Injection also gives you the ultimate control of your engine when using the Advanced Tuning features. These features give you the ability to easily adjust your ignition curve specifically for your engine setup, eliminating the hassle, complexity and limitations of the standard distributor advance mechanism. This type of control will result in a smoother idle, faster acceleration, better peak power, improved fuel economy and the ability to control detonation, all with the touch of your finger in the E-Tuner 4 app. The E-Tuner 4 App is available to download for Android and Apple iOS powered devices.



WHY IS PRO-FLO 4 EFI BETTER?


Throttle Body style EFI Systems feature fuel rails and injectors mounted directly to a throttle body. This design delivers the fuel into the air flow stream in the plenum similar to a carburetor. It’s the most universal type of Electronic Fuel Injection system, but it’s not ideal for high performance engines. Mixing fuel this way allows for it to puddle and condense in the plenum of the intake manifold, a recipe for hard cold starts. Another drawback is the delayed throttle response since the fuel must travel through the intake manifold to the combustion chamber. This can also cause the air/fuel mixture to separate as it flows to the cylinders, resulting in an uneven mixture between cylinders. Typically, the center cylinders run slightly richer than the outer cylinders, hindering tuning for peak fuel economy and peak performance. The OEM’s only utilized throttle body style injection for 9 years before transitioning to sequential port fuel injection for improved drivability and efficiency.

Pro-Flo 4 EFI Systems feature a high performance Edelbrock intake manifold with a 1,000 cfm throttle body, fuel rails and individual injectors for each cylinder. Key to the improved performance of a system like this is the fuel injector location, which is at the end of the runner on the intake manifold right before the air flow stream enters the combustion chamber. This location provides a more efficient mixture control thats unaffected by varying intake manifold runner temperatures and length. The fuel injector is also timed with the intake valve opening, giving the ultimate control and is the most efficient way to deliver fuel into your engine. This design produces the best fuel atomization and precise distribution to each cylinder for the ultimate performance.
