When a fix is simple, reliable, and affordable, you do it. The BD Diesel Killer Grid Heater addresses the well-known 6.7L Cummins grid heater failure—without deleting heat output, without special tuning, and without breaking the bank. It’s a stock-function, emissions-compliant upgrade that’s usually in stock and ready to ship.
From 2007 onward, the 6.7L Cummins routes up to ~200 amps through a small bolt and nut inside the intake grid heater. Over time that connection can deteriorate, arc, and break off. When it does, that nut can drop into the engine, risking catastrophic damage to the piston, head, and valves.
Many “solutions” out there simply remove or downsize the heater element. That reduces heat output, hurts cold starts, and often requires tuning. BD’s approach is different: keep the factory heater’s full output—but eliminate the failure point.
Some competing “fixes” replace the grid heater with pricey intake swaps that cut heater output and often rely on tuning to mask the change. That’s a problem in cold climates and a headache for emissions checks. The BD Killer Grid Heater:
