Volvo D13 & Mack MP8 13.0L EPA10 E3.5 Unit Injector Set of 6 | Alliant Power AP55012 Remanufactured
This is the Alliant Power AP55012, a set of six E3.5 electronic unit injectors remanufactured by Alliant Power for the 13 liter Volvo D13 (D13H) and Mack MP8. It is sold as a set: one box does the whole engine, with six injector cups, six hold down bolts and twelve O-rings. Each injector replaces Volvo and Mack 22027808, 21458369, 21119665, 21599153, 21092434, 85003658, 85013611, 85013612, 85013160, 85143382 and 85143385, the same numbers as the Delphi EX631079 single injector. Catalogs list those numbers for the EPA10 / OBD13 emissions level, which some write as US13. A refundable core applies to the set.
The D13 and MP8 used more than one E3.5 injector. The later EPA14 (GHG) engines are listed under different numbers: Volvo 22479124 and 85020428, Delphi EX631085. The 11 liter Volvo D11 and Mack MP7 are listed under a different injector again. Before you order a full set, send us the Volvo or Mack number on one of your old injectors and your engine serial number. We will confirm the set matches your engine.
