7.3 Stage 1 Injectors

Powerstroke 7.3 stage 1 Full Force Diesel performance injectors fits the 1994-2003. 

The injectors in the 94-97 Powerstroke will increase horsepower from 75-125hp to the rear wheels with a custom tuned performance chip. The stock AA injectors for the 94-97 OBS Powerstroke flow approximately 90cc of fuel.  The stage 1 injectors can double you fuel flow reaching up to 180cc.  The gain in power in substantial with the stage 1 injectors over the stock injectors.  Stock AA injectors are limited by fuel delivery and even with performance tuning are limited to 235hp.  With the extra fuel of the stage 1 injectors the increases can be up to 350hp total horsepower.  In the 94-97 OBS we recommend choosing the 160cc injectors if you have a stock turbo and stock intercooler.  With the addition of the turbo upgrade or intercooler we suggest the 180cc option.  

In the 99-03 Powerstoke you will have to run a custom programmed chip to make the transition from split shot injection to the new single shot injection.  Horsepower increases from 50-75hp and mileage increase from the more efficient single shot design.  The stock AD injector in the 99-03 will flow approximately 145cc of fuel but with with the split shot design 10cc of fuel is wasted in the pilot injection cycle.  With that said, the effective flow rate of the AD stock injector is 135cc.  We recommend the upgrade to 180cc in the 99-03 Superduty with the results of about 75hp over a stock truck with a performance chip.

Each injector comes with a new nozzle, new *Tungsten coated plunger and barrel assembly, new springs, and as needed more internal wear parts are replaced if needed.  Flow tested and matched down to a 1% variation at idle and wide open flow.  New internal and external O-rings are installed.

Please note- a custom tuned chip is required to make these injectors work properly in your truck.

We recommend installing new glow plugs when installing injectors.  Theses are easy to change at the same time as the injectors.  However vlave cover gaskets are reusable and should be fine unless the harness is damaged.

We do not charge any other fees to repair your core injectors.  Please note some of the other companies charge for bad parts on top of the advertised price and do not use new plungers and barrels or nozzles in their injectors.   Injectors that have ran vegetable oil leave a damaging coating and will not be accepted as cores. 

*Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

Tungsten carbide is approximately two times stiffer than steel, with a Young’s modulus of approximately 530–700 GPa and is much denser than steel ortitanium. It is comparable with corundum 

Tungsten coating in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond powder, wheels, and compounds.
