The fuel injector is the most essential element when running a performance EFI system. The engine cannot reach its maximum potential if the injectors that the engine management system controls are not delivering the proper amount of fuel. Competition electronic fuel injectors are available in varying flow rates for all applications of high performance to racing specifications in auto and marine. Unless stated otherwise, static flow rates (lb/hr or cc/min) are determined at 43.5 PSI (3 bar) fuel pressure.
