If you are experiencing a rough idle, misfire, or check engine light, this could be the problem. Earlier fuel injectors for the N54 have been a common failure item, this is the most up to date injector for the N54 engine. It is highly recommended to replace older injectors also if your car is modified or you plan to modify it.

Important information to consider when replacing injectors:

• It is recommended to replace at least 3 injectors at a time, replacing all injectors in a cylinder bank, instead of mixing and matching.
• If ALL injectors in a bank are index 11 or greater, injectors may be replaced individually with a new injector.
• If your stock injectors are index 10 or less, all 3 injectors per bank must be replaced. For V8s, all four in that bank must be replaced.
• Vehicles with old injector 7585261 will need to inspect their existing injectors to determine if these can be replaced individually. 
• Replacement also requires 13537564751 for each injector.
