Description
The BD Diesel 1041520 Killer Grid Heater Upgrade Kit is engineered to fix a critical design flaw in the intake‑grid heater circuit of 2007.5–2024 6.7L Cummins diesel engines. The stock grid heater system passes roughly 200 amps through a small bolt and nut — a known weak point that can corrode, arc and eventually break. If that bolt drops into the intake manifold, it can cause catastrophic engine damage (pistons, heads, valves). This kit upgrades the electrical connection so the heater retains full heat output while eliminating the problematic nut and bolt, dramatically reducing the risk of internal engine failure.
Features:
- Eliminates the failure‑prone grid‑heater bolt and nut that can lead to dropped metal and engine damage
- Retains full heat output with the stock intake grid heater — so no loss of functionality
- Straightforward installation with pre‑fabricated hardware, gaskets, and special tools included
- Self‑locking threads built into the lower busbar prevent the connection from backing out over time
- Emissions‑compliant and requires no tuning or calibration after installation
