Alliant Power AP66957 is a G2.9 injector remanufactured by PurePower Technologies for the 2010 to 2014 Navistar MaxxForce DT rated 210 HP to 225 HP. It crosses to Navistar 1884057C92, 1884058C2 and 5010986R91. Alliant lists it for International 4300, 4300LP, 4400, 4400LP, 7300 and 7400 (2010 to 2014) and the 3200 (2010 to 2011) with the MaxxForce DT.
Installing it requires removing the high-pressure oil rail, and Alliant calls for the AP0025 high-pressure oil rail seal kit when the rail goes back on. Alliant lists AP66955 for 2010 to 2014 MaxxForce DT engines rated 215 HP to 300 HP, so the two ranges overlap at 215 HP to 225 HP. Match the Navistar number on the old injector: 1884057C92 or 5010986R91 is AP66957; 1890055C92 or 5010715R91 is AP66955.
