-10% HP Universal Retrofit Kit, Dominator Carburetor Intake Manifolds

If you have a carbureted engine, want to install electronic fuel injection, but are looking for something more than a throttle-body injection setup, these EFI retrofit kits are an excellent choice. Besides including the HP ECU, harness, and throttle body, this kit comes with all of the the essentials to convert your carburetor-style manifold to EFI, including fuel injector bungs, fuel rail, injector clips, and fuel pressure regulator. Don't worry, the key sensors (Bosch O2, coolant temperature, air temperature, 1-BAR MAP) are all there too. It's even got a block-off plate for your mechanical fuel pump, if you require that.

The throttle body in this kit is Holley's billet aluminum 2000 CFM Dominator-style throttle body, equipped with throttle position sensor and Idle air control hardware. Complete instructions take you step-by-step through the process of manifold preparation, fuel system design, plumbing, throttle body and O2 sensor installation, and wiring. And we're always standing behind you with our Holley certified Tier-III installation technicians.
