Built for performance and ultimate reliability. Not only does this upgraded plenum delete the dangerous factory grid heater element—saving your engine from the dreaded "killer nut"—but its widened internal geometry significantly increases air volume entering the intake manifold.
When you upgrade your turbo or injectors on a 2007.5-2024 Dodge Ram 6.7L Cummins, the factory grid heater becomes a massive bottleneck. The OEM unit acts like a thick waffle iron right in the middle of your intake stream, choking off the dense, cold air your diesel desperately needs.
The High-Flow Grid Heater Delete Plenum from Delete.Autos completely revolutionizes how your engine breathes. By stripping out the thick factory heating element and redesigning the internal plenum geometry, this high-flow plate forces more air into cylinders 1 and 6, drastically lowering your Exhaust Gas Temperatures (EGTs) and increasing your air density.
This high-flow plenum delete is a direct bolt-on upgrade for all 2007.5 to 2024 Dodge Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins Turbo Diesel. You will reuse your factory bolts for installation. Please note that removing the factory grid heater will cause a Check Engine Light (CEL) on most trucks unless accompanied by custom ECM tuning.
