The included seal and O-ring support proper sealing at the injector interface, while the direct injection design aligns with modern BMW GDI engine demands.

Common Problems This Part Can Address

• Hard starting caused by poor fuel delivery at the injector
• Rough idle from inconsistent gasoline atomization
• Misfire conditions related to injector performance
• Fuel trim imbalance from a restricted or failing direct injector
• Loss of power or hesitation under load in GDI-equipped BMW engines

Installation Notes and Tips

Verify engine code and VIN-specific fitment before ordering, especially on BMW M, X, and Alpina applications. This injector uses a bolt-in attachment method and OE-style connector shape, so electrical and sealing surfaces should be inspected carefully during service. Replace worn seals and confirm the fuel system is depressurized before removal or installation. Because this is a direct injection component, cleanliness during installation is important to protect the injector and the high-pressure fuel system.
