This is the Delphi EX631008, an A type electronic unit injector for the Volvo D12 12.1L, remanufactured by Delphi. Catalogs list it for the D12C version of the engine. It replaces Volvo 8113411 and 8170998, and the Delphi number is BEBE4B12003. It is sold one at a time, and a refundable core applies.
Delphi lists several A type injectors for the D12, each under different Volvo numbers. This one is not the same as the EX631004, which replaces Volvo 3964404 and 8113092. Order by the Volvo or Delphi number on your old injector, not by engine model alone.
Confirm Fitment Before You Order
The Volvo D12 takes several A type injectors with different Volvo numbers (Delphi EX631002, EX631003, EX631004, EX631006, EX631007 and EX631008 among them), and catalogs do not cross one to another. Send us the Volvo and Delphi numbers from your old injector and the engine serial number, or call 530-668-0818. We will confirm the exact match at no charge before anything ships.
