1989 to 1998 Dodge 5.9L Cummins Diesel Air Intake Heater Grid 

KLM Performance offers this part as a Brand New OEM Cummins replacement heater grid intake relay for the complete repair of your poor start condition.

Cummins 3929108 relay applications:

  • 1989 to 1993 Cummins 5.9L 12 Valve diesel engines.
  • 1994 to 1998 Cummins 5.9L 12 Valve diesel engines.

The Cummins 5.9L 12V diesel engines do not use glow plugs during the cold startup process.

  • Longer crank times in cold weather.
  • Multiple engine cranking periods before the engine fires.
  • Increased white smoke during cold starts.
  • A hard-to-start condition is present during cold weather.

NOTE: The replacement of the Intake Heater Grid or Bracket on 1989 to 1998 5.9L Cummins powered trucks works if the relay isn't integrated into the intake plenum on the 12 Valve 5.9L Cummins diesel.
