We list the engine platform a part is built for. That is not year-and-trim application data, so it does not confirm a fit on your specific vehicle.

  • Est. install labor: 14.0 hrs — $1,750 at $125/hr. Pick Install at HRC and a 20% labor deposit ($350) is due at checkout; the balance is due at completion.
  • An estimate for a stock vehicle, not a quote — we confirm it in writing when you book, before any labor is authorized. Seized hardware, prior modifications, diagnosis and machine work are quoted separately; tuning is arranged through our tuning partner. Questions: (714) 202-7886.

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.

  • Supports 650 hp, 4150 Flange, 1000 CFM, Classic looks of a traditional carburetor, Highly refined base tunes to chose from plus self learning technology, Bosch LSU 4.9 Wideband O2 sensor included, Complete Spark Control, Built in ignition coil driver, Built in Bluetooth communication, Easy to use E-Tuner app for Android and IOS, CAN Communication, Simple 4 wire hookup. Intended to be used with engines that have been transplanted or swapped into an uncontrolled or pre-pollution controlled vehicle, as defined above. They are not legal for use on pollution controlled vehicles.
