Product Description
The BD DIESEL 1041520 Killer Grid Heater Upgrade Kit is a purpose-built solution to eliminate one of the most dangerous failure points in the 2007.5–2024 Dodge/Ram 6.7L Cummins intake grid heater system. From the factory, the grid heater electrical connection forces extremely high current through a small nut and bolt inside the intake. Over time, that connection can deteriorate, arc, and break—allowing metal to drop into the engine and potentially cause catastrophic piston, head, and valve damage.
This kit upgrades the faulty electrical circuit by eliminating the problematic internal bolt and nut while retaining full factory grid heater functionality. It’s designed for straightforward installation with no tuning required and includes the replacement hardware, gaskets, and special tools needed to complete the job properly. This is the go-to preventative upgrade for 6.7L Cummins owners looking for maximum reliability without sacrificing cold-start performance.
