Fuel Injectors

The fuel injector is an electronically controlled valve that is supplied with pressurized fuel by the fuel pump and when energized atomizes the fuel into a fine mist so that it can burn easily in the vehicle’s engine.

Multi-Port Fuel Injectors

GM’s Vortec engines come with a Sequential Port Injection System (SCPI). Our Multi-Port Fuel Injection (MFI) system has several advantages over the original Sequential Central Port Injection (SCPI) system, including port fuel delivery and high reliability, better hot starts and reduced vapor emissions, and faster prime on hot restarts.
