Air Intake Heater for Ram 2500 Ram 3500 (2011-2019) 6.7L

Heavy-Duty Air Intake Grid Heater for 2011-2019 Ram 2500, 3500 (DJ/D2)

What it Does: The Air Intake Grid Heater preheats incoming charge air on cold starts for the 2011-2019 Ram 2500 and 3500 to facilitate rapid diesel ignition and eliminate excessive white smoke.

The Stock Ram 2500, 3500 Grid Heater Degradation

Extreme thermal cycling, continuous high-amperage draws, and engine vibration degrade the factory intake heater element on the 6.7L Cummins ISB over time. Prolonged exposure causes electrical resistance failure, terminal post degradation, and broken internal heating elements. When this element fails open or loses conductivity, the engine experiences extended cranking, unburned fuel wash, rough cold idling, and failure to trigger clean compression ignition in sub-freezing ambient temperatures.

The Engineering Solution

Manufactured to OEM dimensional tolerances, this direct-replacement grid heater utilizes a high-efficiency resistive metal heating element secured in a rigid stamped-metal housing. The unit features standard single-side terminal orientation to integrate seamlessly into the factory wiring harness without harness modification. Included dual high-density composite intake gaskets seal the heater block against the intake horn and plenum face, completely preventing boost leaks and particulate ingestion under high manifold pressure.
