How to Find Your Fuel Injector Part Number

Every fuel injector carries an identifier that ties it back to a specific vehicle application. The number is typically printed on the body of the injector, either laser-etched into the metal or on a small foil label near the connector.

To locate it, first ensure the engine is cool and disconnect the negative battery terminal. Remove the engine cover, and locate the fuel rail. The injectors sit between the rail and the intake manifold.

Write down the full number including any dashes and letters. Small differences (a trailing letter, or a suffix like '-A01') can indicate a different application year or emissions calibration.

Enter the number into our Search by Part Number page — the search recognizes common formatting differences (spaces, dashes, capitalization). If you receive multiple partial matches, use the Fitment Assistance form to have our team verify the correct listing for your vehicle.
