A high percentage of Ram owners with the 6.7 Cummins Engine are removing the Grid Heater due to a weak bolt that, over time becomes weak and falls down into the intake of the engine. The bolt will go directly into the engine block and cause catastrophic damage. There is an aftermarket fix which is a heater element installed into the intake horn itself instead of directly on top of the flat intake surface.
