Why Upgrade the Grid Heater on a 6.7 Cummins?
If you’ve owned a 6.7L Cummins long enough, you’ve probably heard about the infamous heater grid bolt failure. The issue stems from the electrical connection running into the intake manifold. When the grid heater activates, it sends 200 amps through a small bolt and nut that can eventually degrade, arc, and break off inside the intake.
That bolt can end up inside your engine, causing catastrophic failure, damaging pistons, valves, and heads. The BD Killer Grid Heater Upgrade Kit addresses this exact flaw by eliminating that internal nut and bolt entirely, while still retaining full factory heater function.
What Makes the BD Killer Grid Heater Kit a Smart Upgrade?
This isn’t just a patch job. BD’s solution eliminates the risk without needing any tuning, software changes, or extensive intake modifications. You keep the stock heater grid function, get cleaner electrical routing, and avoid the nightmare of a bolt failure. The kit is emissions-compliant and comes with all hardware and special tools for easy installation.
