KLM Performance offers this part as a Brand New OEM Moparheater grid intake relay to completely repair your poor start condition in cold weather. The Mopar 5187880AC intake heater grid relay is a vital part of the operation of the intake heater grid.
The Cummins 6.7L diesel engines do not use glow plugs during the cold startup process. The Cummins diesel engine is equipped with a relay that is used to activate the intake heater grid, which is located directly between the air horn and intake manifold. The intake heater grid heats the incoming air charge during a cold startup to ensure a quick start in cold weather. The replacement of the Intake Heater Relay or Mopar Bracket on the 2019 to 2020 Dodge Cummins requires only one Mopar 5187880AC relay.

More frequent crank periods before the engine fires.
Increased white smoke during cold starts.

Product Note: Cummins diesel engines use an intake manifold air heater element assembly which is located at the top of the intake manifold. A Relay Air Intake Heater controls this air heater element used to pre-heat incoming air charge to the intake manifold. This heated air charge is used to aid in starting your Cummins diesel engine when temperatures drop and improve drivability with cold outside temperatures.
