Common Issues This Injector Can Address

  • Hard starting caused by poor fuel delivery at the injector
  • Rough idle from inconsistent direct injection performance
  • Misfire conditions related to a worn or restricted injector
  • Fuel trim imbalance from uneven cylinder fueling
  • Loss of throttle response tied to injector flow issues

Installation Notes and Tips

Verify engine code, injector style, and VIN-specific fitment before installation. Direct injection systems operate at high pressure, so fuel pressure should be relieved and the system inspected for contamination before service. Replace injector seals and confirm proper seating to help prevent leaks and drivability concerns. Bosch 62809 is listed for one-per-cylinder applications on the supported Infiniti models.

Quality Assurance

Bosch is a recognized OE leader in fuel systems technology, and this injector reflects that background in gasoline fuel injection service parts. The Bosch 62809 fuel injector is built for direct injection applications where precise fuel metering and reliable operation matter.
