6.7 Cummins Killer Grid Heater Upgrade Kit | BD-Power 1041520

Fix the 6.7 Cummins grid-heater connection before a loose nut drops into the engine. BD-Power 1041520 replaces the factory stud and nut inside the intake with a self-locking lower busbar and an M8 bolt fastened from the top. The stock heater stays in place and still puts out full heat. About 200 amps used to run through that small internal fastener until it arced, melted, and fell into a cylinder. This kit removes that failure point. Emissions compliant in all 50 states.

This is not a heater delete. The factory grid heater still works for cold starts. If a 2007.5–2024 6.7 Cummins still has the original internal nut, the BD-Power 1041520 Killer Grid Heater Upgrade Kit is the hardware fix built to keep that nut out of the engine.
