6.7 Cummins Grid Heater Delete

Why Does Your 6.7 Cummins Need a Grid Heater Delete?

High Amperage Grid Heater Relay and Contactor Failures

The stock 6.7 Cummins grid heater pulls a massive electrical load on every cold start. The factory relay and contactor are a known weak point that can weld shut or overheat, and in worst cases the high current path has been tied to under-hood fire risk on certain model years. A delete plate removes the heater element and the constant amp draw from the equation.

Restricted Intake Plenum Airflow

The grid heater sits right in the intake plenum as a serpentine heating coil. That coil is an airflow obstruction that disrupts the smooth charge path into the manifold. Swapping it for a solid 6061-T6 billet plate opens the plenum and lets the turbo breathe without the factory restriction.

Cracked Plenum Welds and Leaky Heater Elements

Years of heat cycling crack the plenum housing and loosen the heater element seals. Once the seal leaks, you get unmetered air and a rough idle. Our delete plates replace the entire compromised section with a precision-sealed plate so the intake tract stays honest under boost.

What Can a Grid Heater Delete Solve?

Restore Full Plenum Airflow

Machining the heater coil out of the airflow path gives the 6.7 Cummins a cleaner, less turbulent intake. That translates to crisper throttle response and a small but real gain in turbo efficiency on both daily drivers and dedicated tow rigs. Once the plenum is open, run a 6.7 Cummins CCV reroute so crankcase oil mist stays out of the freshly cleaned intake.

Eliminate a Known Electrical Failure Point

By removing the grid heater element, you also remove the constant high-amperage demand on the relay and feeding wiring. Pair the plate with a relay delete harness and the under-hood electrical gremlins disappear.

Simplify the Intake for Easier Service

Fewer parts in the plenum means fewer things to crack, leak, or fail on the side of the road. The billet plate is a set-and-forget upgrade that survives extreme under-hood heat. For a heavier-duty option on extreme-duty plenums, see the 6.7 Cummins grid heater upgrade.

FAQs about 6.7 Cummins Grid Heater Delete

What does a 6.7 Cummins grid heater delete actually do?

A 6.7 Cummins grid heater delete replaces the factory intake air heating element with a solid CNC-machined 6061-T6 billet aluminum plate.
This opens the intake plenum, removes a restrictive coil, and cuts the heavy electrical amp draw from every cold start. The result is cleaner airflow into the manifold and one less failure point on the 6.7 Cummins.

Which trucks does the 6.7 Cummins grid heater delete fit?

The delete plate covers the 6.7L Cummins found in Ram 2500 and Ram 3500 trucks from 2007.5 through 2024.
The plenum plate variant fits 2008 through 2024 Dodge Ram and Ram 2500 and 3500 models. Always match the handle to your exact model year before ordering.

Do I need a tune after installing a 6.7 Cummins grid heater delete?

No tune is required for a grid heater delete on the 6.7 Cummins.
The intake heater is not an emissions control device, so removing it does not trigger a fueling or regen strategy change. You can bolt it on and drive without flashing the ECM.

How hard is the 6.7 Cummins grid heater delete install?

The install is a straightforward intake plenum job that most home mechanics finish in roughly one to two hours.
You remove the intake horn, unplug the heater element, drop in the billet plate with the supplied Viton O-ring, and torque it down. Basic hand tools and a socket set are all you need.

Will a grid heater delete cause a check engine light on my 6.7 Cummins?

In most cases, the 6.7 Cummins does not throw a code from removing the intake heater element alone.
Because the heater is not a monitored emissions component, the ECM usually stays happy. If your truck has an aftermarket cold side or relay delete, verify those circuits are capped properly.

What material is the 6.7 Cummins grid heater delete plate made from?

Our plates are CNC-machined from 6061-T6 billet aluminum for a precise seal against the plenum.
Each plate ships with a high-temperature Viton O-ring that holds up under sustained under-hood heat and boost. The finish is cut to resist corrosion on both daily drivers and work trucks.

Is a grid heater delete the same thing as an intake heater delete?

Yes, on the 6.7 Cummins the terms are used interchangeably.
The grid heater and the intake air heater are the same component sitting in the plenum. Whether a listing says grid heater delete or intake heater delete, the part does the same job of blocking off that heater element.

Why do 6.7 Cummins grid heaters fail and need replacement?

The factory grid heater draws heavy amperage through a relay that can weld or overheat over time.
Heat cycling also cracks the plenum welds and loosens the heater element seal, leading to unmetered air and rough idle. Replacing it with a billet delete plate ends that failure cycle for good.

Is a 6.7 Cummins grid heater delete street legal, and does it affect my warranty?

The intake grid heater is a cold start air heating element, not an EPA-regulated emissions control device like EGR, DPF, or DEF.
Removing it is a common street reliability upgrade, but you should always check your local and state regulations before modifying any vehicle. Every plate is covered by free shipping, a 1-year warranty, and our 45-day return policy so you can order with confidence.

What is the best grid heater delete for a 6.7 Cummins?

The best grid heater delete for a 6.7 Cummins is a CNC 6061-T6 billet plate with a sealed Viton O-ring and a clean plenum fit.
Look for a plate that matches your exact year range, ships with hardware, and is backed by a real warranty. Our Ram 2500 and 3500 delete plates are built to that standard.
