Volvo D16 & Mack MP10 16L E3.5 Evolution Unit Injector | Delphi EX631087 Remanufactured (21457953)
This is the Delphi EX631087, an E3 series electronic unit injector remanufactured by Delphi. It is the E3.5 Evolution injector for the 16L Volvo D16 and Mack MP10. It replaces Volvo and Mack 21172432, 21306972, 21457953, 21683459, 22027810, 22717954 and 22717957, and service numbers 85003666, 85013099, 85013161, 85013613, 85013720, 85013721, 85020857, 85020858, 85148517 and 85148518. It is sold one at a time, and a refundable core applies.
Delphi lists three E3 injectors for the 16 liter: the E3.3 unit (EX631030, Volvo 21457951), this E3.5 Evolution unit, and the E3.5 GHG unit (EX631086, Volvo 22479125). The 11 liter and 13 liter engines take their own injectors as well, for example Delphi EX631078 and EX631079. Go by the Volvo or Mack number on your old injector, not by the look of the body.
