Complete set of eight remanufactured AA injectors for the OBS 7.3L Power Stroke, supplied with the gaskets and harness parts the job actually needs.
HEUI injectors wear as a set. By the time one is misfiring the others are usually close behind, which is why these are sold as eight rather than singly. Rough idle when cold, white smoke on start-up, and a miss that clears as the engine warms are the usual signs.
This is the AA-code injector — the original single-shot design fitted to 1994.5–1997 non-California trucks. The AB injector is a split-shot that fires a small pilot charge before the main event and flows considerably more fuel; it went into 1997 California emissions trucks and early 1999 builds. The two are not interchangeable, and fitting AB injectors to an OBS truck without matching tuning will not run correctly.
The kit includes the valve cover gaskets and harnesses, which have to come off to reach the injectors and are routinely damaged on removal.
