The BD Diesel Killer Grid Heater Upgrade Kit provides a solution to a known issue in the 6.7L Cummins engine. This problem involves the electrical connection of the intake grid heater. The design of the original equipment allows 200 amps to pass through a small bolt and nut within the intake. Over time, this connection can deteriorate, leading to arcing and breakage. When the nut breaks off, it can fall into the engine, potentially causing significant damage to components such as the piston, cylinder head, and valves.
Current solutions in the market often come with high costs, may reduce the heat available to the engine, typically necessitate tuning, or exhibit reduced effectiveness in cold environments. This upgrade kit addresses the original electrical circuit by removing the problematic bolts and nuts from inside the intake manifold. It maintains the original functionality of the grid heater, offers a cost-effective alternative, and is designed for straightforward installation.
