Cross-Referencing Parts for the 2009 International Prostar 15.0L DIESEL
Every one of the 8 parts on this page was matched to the 15.0L DIESEL engine specifically — not to the 2009 International Prostar in general. That distinction is the whole point: application data is published per engine, and parts that interchange across engines are the exception, not the rule. The 4 brands represented here include OEM-grade suppliers and aftermarket manufacturers, each with its own part number.
Use the part numbers as your verification layer. Match a part's number against the old part before ordering, or search a number you already have to confirm it belongs to this engine. Where an OEM number has been superseded or discontinued, the same-fitment parts in its subcategory point to current equivalents.
