The POWERJECTION I™ from Professional Products is a throttle body based Electronic Fuel Injection system with features never seen before. This unit looks exactly like a carburetor and is free of those ugly wires and fuel rails that conventional fuel injection systems include.

With this unique system, engines up to 500 HP do not require a fuel return line. The Engine Management System (EMS) is a self-learning unit, which eliminates the need for programming. That option is still available, but not needed. Simply install the system and drive away. Within 30-minutes the computer has taught itself and dialed in your engine. This system from Professional Products can be used with forced induction as either a blow-through or a suck-through.

The POWERJECTION I™ system features a billet or cast aluminum throttle body with four port-style injectors. These injectors cannot be seen under the two injector shrouds that look very similar to a standard 4-bbl carburetor. Because the unit is the identical dimensions of a standard 4150 style carburetor, it is a direct bolt-in swap on any vehicle equipped with a square bore 4-bbl carb.

The complete kit includes the EMS, inline electric fuel pump, fuel filter, complete sensor pack, wide-band O2 sensor with a clamp style exhaust bung, and a very comprehensive installation manual. Installation only takes a day!
