The K&N 20-0003 Electronic Carburetor Injection (ECI) system is the solution to every day carburetor issues. Using an included wideband O2 sensor, the system reads the air/fuel ratio in the exhaust and adds fuel if a lean condition is detected. Say goodbye to cold start issues, pumping the gas, priming, and flooding. It will also help support carburetors that have issues during idle and off-throttle conditions. The kit comes with the ECI carburetor plate, fuel block with fuel injector, weatherproof ECU, wire harness, O2 sensor, and all the gaskets and hardware required for install. Thanks to its supplemental design, the system installs with your current carburetor setup. Installation can be completed in a few hours with common tools. The K&N ECI system is also great for drag racers who race carbureted engines. It is compatible with all fuel types, including E85. It is an ideal solution for marine applications, as the ECU is weatherproof and can be mounted just about anywhere. Say goodbye to headaches associated with carbs and don't worry about switching to EFI. The K&N 20-0003 fits Holley Dominator style carburetors.
