6.7L Cummins Killer Grid Heater Upgrade

Quality by Design. Monster by Nature.

The factory grid-heater setup can place a high-current bolt/nut connection inside the intake. If that hardware deteriorates, it can arc, loosen, or break—creating a worst-case risk of debris entering the engine. This upgrade relocates the high-amp connection outside the intake while retaining stock grid-heater function for cold starts.

Fits 2007–2024 Ram 6.7L 2500–5500 (Pickup + Cab/Chassis) Starting at $181.76

Why the 6.7 Cummins Grid Heater Issue Matters

On many 6.7L Cummins trucks, the factory grid-heater setup routes very high current through a small fastener connection inside the intake. If that connection deteriorates, it may arc, loosen, or fail. The goal of this upgrade is simple: keep the heat, remove the in-intake risk.

Owners want a preventative solution that doesn’t compromise cold-start performance.
A “delete” can reduce winter drivability—this kit is designed to retain factory heating behavior.
Relocating the connection externally is a direct way to reduce worst-case intake debris risk.
Broad fitment coverage across pickups and cab & chassis platforms makes it a “one-page” solution.

Upgrade vs delete Built to maintain the grid heater’s role for cold climates—without leaving high-amp hardware inside the intake path.

Preventative mindset Ideal if you’re addressing reliability before symptoms appear (especially on work trucks).

How Monster’s Killer Grid Heater Upgrade Works

Instead of relying on a high-amp connection located inside the intake, this kit is designed to relocate that current path externally. The result is a cleaner risk profile while preserving the grid heater’s intended job during cold starts.

Relocates the high-current connection so the vulnerable fastener is no longer in the intake stream.
Designed to retain the factory heater function—no tuning required.
Includes the hardware/components needed for a straightforward, reliable installation.
Built for common Ram 6.7L applications, including pickups and cab & chassis.

Best for Daily drivers, tow rigs, fleets, and work trucks that can’t afford downtime.

Cold-climate friendly Keeps starting performance and drivability where intake heat matters most.

Installation Overview — What to Expect

Exact steps vary by truck configuration, but the intent is consistent: move the high-amp connection outside the intake and re-establish a clean, secure electrical path. Always follow the product page instructions and torque/fastener guidance provided with your kit.

Plan for a careful, clean work area—protect the intake opening and keep debris out of the engine.
Basic hand tools typically cover the job (plus attention to routing/fastener security).
Verify connections and re-check hardware after initial heat cycles where applicable.
If you’re not comfortable working around intake components, use a qualified diesel technician.

FAQ: Killer Grid Heater Upgrade

What problem does this kit solve?

The OE layout places a high-current fastener connection inside the intake. Over time, that connection can deteriorate and fail. This upgrade relocates that high-amp connection outside the intake to reduce worst-case risk while keeping the heater functional.

Do I need tuning?

No. The kit is designed to retain factory grid-heater behavior and cold-start performance without tuning.

Is this an upgrade or a “delete”?

This is an upgrade. It’s intended to keep the grid heater doing its job, but remove the in-intake high-amp hardware connection from the equation.

What years and trucks does it fit?

2007–2024 Ram 2500/3500 pickups and 3500/4500/5500 cab & chassis with the 6.7L Cummins. When in doubt, confirm by VIN.

What’s included?

The kit includes the components and hardware needed to relocate the high-current connection. See the product page for the exact in-the-box list.

Warranty?
