EZ Fuel Dual Quad

The next generation of the world's simplest self tuning fuel injection system is here. Designed for all applications making up to 650 horsepower, the EZ-EFI Fuel system easily bolts onto any carbureted or multi-port application in a single afternoon, making it the easiest EFI system you will ever install. Simply hook up the system, answer the questions from the improved Setup Wizard on the color touchscreen hand-held unit, and the system will tune itself as you drive. The hand-held includes a variety of display dashes, a clean and easy to use interface and an LED indicator that can alert users to any errors (including overheating) or be used as a shift light. An updated wiring harness features a premium loom, added protective fuses and a streamlined design, while the ECU hardware has been updated to provide added protection against electrical/ignition noise and hardware damage. FAST EZ-EFI Fuel now features a die cast and black powder-coated four-injector throttle body with integrated fuel rails. It provides even better fuel distribution and more airflow than the original, and NO manifold replacement is needed. In addition to matching any 4150-style carbureted manifold, the EZ-EFI Fuel Self Tuning Fuel Injection System also works with your original carb-style throttle linkage and features OEM sensors, including standard GM versions available at any auto parts store. What?s more, it works with all ignition setups ? including HEI. EZ-EFI Fuel can be installed easily in an afternoon and is a ?must have? for your street rod or muscle car. For more aggressive applications, the EZ-EFI Dual Quad Upgrade Kit is capable of supporting 1200+ horsepower engines with dual quad carburetor-type manifolds. In addition, the Multi-Port Retro-Fit EZ-EFI allows owners of multi-port fuel injected applications to experience the benefits of EFI with no limit on horsepower because the system is based on each customer?s supplied injectors.

Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
