AA Injectors

Designed for 1994–1997 non-California trucks, these injectors feature a proven single-shot design with a 90cc fuel delivery rate, ideal for stock replacements and restorations.

AB Injectors

Used in 1997 California-emissions trucks and all early-1999 models, AB injectors utilize a split-shot design and flow 130cc of fuel for smoother operation and improved drivability.

AC Injectors

Found exclusively in high-torque T444E applications and never used in Powerstroke engines. These injectors share internal components with AB injectors but use a single-shot plunger and barrel, delivering increased fuel flow of 160cc.

AD Injectors

The standard injector for late-1999 through 2003 Powerstroke and T444E engines. These split-shot injectors offer a well-balanced combination of performance, reliability, and everyday drivability.
