What This Injector Helps Address

• Hard starting caused by a worn or restricted direct injector
• Rough idle from uneven fuel delivery in a GDI engine
• Misfire conditions related to poor injector spray performance
• Fuel trim imbalance from inconsistent injector output
• Loss of throttle response from inadequate high-pressure fueling

Installation Notes and Tips

Confirm engine code and injector part number before installation. Direct-injection systems operate at high fuel pressure, so relieve fuel pressure and follow the service procedure for the specific vehicle before removing the injector. Inspect the injector bore, seals, and rail connections during service, and replace any damaged sealing surfaces before reassembly. After installation, clear fault codes and verify fuel trims, idle quality, and leak-free operation.
