This OE FIX fuel injector driver module (IDM) is designed to match the fit and function of the original module on Ford trucks utilizing the 7.3L Powerstroke under the hood, but it's also been re-engineered for longevity. A new case was designed without a vent, a common ingress point for water on the original IDM in these trucks. The case seam is also closed with a larger volume of sealant, greatly reducing water damage from another common entry point. Our all-new construction also takes the gamble out of replacing your driver module with a used or remanufactured unit, since what few available cores remain are showing their age.
