2003-2007 Powerstroke Fuel Injector (II901-R1)

The Industrial Injection II901-R1 is a performance-grade fuel injector for the 2003-2007 6.0L Powerstroke. It is built on a factory-machined solid body — no welds, no plugs — which eliminates the check-ball pressure failure mode. Internally it carries 100% new precision-fit upgraded spool valves with vented-slot coil technology, a new harness connector, and new plungers and nozzle assembly. Copper washer and injector o-ring kits are included for installation.
