Cast EFI Throttle Body

This Throttle Body is rated at 1200 CFM. It features a linkage arrangement that is very similar to a Holley carburetor so that the various usual cables will all connect to this throttle body. It is designed with a special adapter that permits the use of either a Ford or a GM throttle position sensor. This throttle body is substantially less expensive than competitive models

Engine Management System (EMS)

This is not a reworked or modified factory unit. It is state-of-the-art aftermarket EMS designed and engineered from scratch by Professional Products’ personnel. We feel that this is the most advanced aftermarket engine management system available. It can be adapted to work with many existing fuel injection systems, including many of the early OE systems which leave much to be desired. Are you dropping a late model injected engine into an early vehicle and you need an EMS to make it work? We have just what you need in our Stage 2 unit.

EFI Fuel Filter

Although similar in design to many EFI filters, this one has one very important feature. It has 1/4-NPT pipe threads on both ends so it accepts a variety of stock fuel fittings.

EFI Inline External Fuel Pump

These pumps are available suitable for engines up to 700+ hp. They are very similar in design to popular Walbro or Airtex pumps but feature 1/4-NPT inlet and outlet ports which allow the use of a wide variety of standard fuel line fittings. The extruded aluminum mounting bracket/heat sink is supplied with the pump.
*Reduce horsepower numbers by 5% for supercharged or turbocharged applications and by 30% for E85.

Special Fittings for use with EFI Components

This selection of fittings will be useful for fuel pump and fuel filter connections or plugging unused ports on Powerjection I.

Fuel Return Kit

If your vehicle does not already have a return line to the fuel tank, and your system requires one, you will need this Return Kit. It includes 25 feet of -6AN stainless braided fuel line, an assortment of fittings, a pre-filter, and main filter plus a regulator.

Billet EFI Throttle Body

For those customers who like the looks and bragging rights to a full billet CNC machined throttle body, we offer several versions.

Sensors for Powerjection EFI Systems
