Description
Protect Your Cummins from Catastrophic Failure
The BD Diesel Killer Grid Heater Upgrade Kit (1041520) addresses a critical, well-known design flaw in the 6.7L Cummins intake. Over time, the factory grid heater nut can deteriorate, arc, and break off. If that nut drops into your engine, it causes extensive damage to the piston, head, and valves. This kit eliminates the problematic internal hardware while maintaining 100% of your factory heat output.
Key Features & Benefits:
-
Complete Engine Protection: Permanently eliminates the failure-prone nuts found in the OE grid heater by fastening directly into the lower busbar.
-
Retains Cold Weather Performance: Unlike other "delete" kits, this upgrade allows for full heat output (2400W) with the stock intake grid heater so you won't have cold start issues.
-
Secure Connection: Features self-locking threads built into the lower busbar to prevent the connection from ever backing out.
-
Emissions Compliant: Fully 50-State Legal and does not require a CARB EO (SEMA Certification No. SC-BDD01-0135).
-
Complete Kit: Includes all required replacement hardware, gaskets, and special tools for installation.
Vehicle Fitment:
-
2007.5 - 2024 Ram 2500 & 3500 (6.7L Cummins)
-
2007.5 - 2024 Ram 3500, 4500 & 5500 Cab & Chassis (6.7L Cummins)
-
Note: 2007-2012 applications require a minor modification (removing a small aluminum tab with a Dremel or hacksaw).
Frequently Asked Questions (FAQ)
What is the 'Killer Grid Heater' problem on the 6.7L Cummins? The factory intake grid heater uses a stud and nut inside the intake plenum that can loosen after repeated heat cycles and vibration. In severe cases, the nut falls directly into cylinder #6, causing catastrophic engine damage.
Will this kit cause a check engine light or require tuning? No! The kit is engineered to retain normal grid heater operation and will not trigger common diagnostic trouble codes such as P2609 or P0542. It requires zero engine tuning.
How long does it take to install the BD Diesel grid heater upgrade? The estimated installation time for this upgrade is approximately 3 hours.
