KLM Performance offers these Dodge Ram Air Intake Relays as a pair of replacement heater grid intake relays.

The Cummins 5.9L diesel does not use glow plugs during the startup process. This Cummins 5.9L engine is equipped with two relays that are used to activate the heater grid which is located directly between the air horn and intake manifold. The heater grid heats the incoming air during the startup process to ensure a quick starting in cold weather.
Warning signs your Dodge 5.9L Cummins Diesel Air Intake Heater Grid Relay needs replacement:
- Engine starting requires longer crank times in cold weather.
- More frequent crank periods before the engine fires.
- Increased white smoke during cold starts.
- You are experiencing a hard to start condition present during cold weather.
The replacement of the Intake Heater Relay on the 2003 to 2005 Dodge 5.9L Cummins requires two Mopar 68188370AA relays. Please make sure your order two of these electrical relays.
