Did you know?

Reducing the level of emissions is critical in today's diesel engines. Delphi is leading this technological revolution with its advanced fuel injection systems.

The leading causes of injector failure include:

  • Poor Fuel Filtration
  • Fuel Contamination
  • Incorrect Installation

It is good practice to confirm the root cause of the failure before installing replacement injectors.
