Genuine OEM International Navistar Injection Pressure Regulator (IPR) Valve

Part Number: 1841086C91

Condition: New Old Stock (NOS). Brand new, never installed. Part comes in its original factory box.

Compatibility: Fits various International / Navistar diesel engines (such as DT466, DT466E, T444E, I530E) and is a direct OEM cross-reference for Ford 7.3L Powerstroke diesel engines (1998-2003).

Please Note:

This is a 100% authentic, original factory part. Due to long-term storage, the protective factory oil inside the plastic wrapping has dried in some spots on the metal body, creating a light film or residue (as shown in the close-up photos). This is completely normal for New Old Stock items, serves as original corrosion protection, and does not affect the performance of the valve in any way.

Please review all high-resolution photos of the actual item and the box to ensure this is the exact part number you need before purchasing.
