1. Introduction

For many owners of 6.7L Cummins engines, particularly those with models from 2007 to 2024, the decision to delete the grid heater is often driven by a mix of performance and maintenance concerns.

The grid heater, designed to aid cold starts by heating the intake air, plays a crucial role in ensuring smooth engine operation in low temperatures. However, over time, it can introduce various issues that impact both the engine’s performance and longevity.

Owners may encounter problems such as component failures, where deteriorated bolts from the grid heater can fall into the intake runner and cause severe engine damage. Additionally, electrical issues related to the grid heater can trigger fault codes, leading to engine performance problems and increased repair costs. These concerns drive many to consider removing the grid heater to improve airflow, reduce maintenance needs, and enhance overall engine reliability.

2. Basic Function of the Grid Heater

2.1. Purpose of the Grid Heater

The 6.7 Cummins grid heater plays a crucial role in cold starts by heating the intake air. This heating helps ensure smooth engine startup in low temperatures and promotes efficient combustion. By raising the air temperature, it aids in stabilizing engine performance during cold conditions.

2.2. Benefits and Drawbacks

While the grid heater assists with cold starts, it can also cause intake airflow restrictions. For those seeking high performance, removing the grid heater can enhance airflow, improving engine efficiency and power.

Curious about the potential issues with the grid heater? Read on to understand common problems and why some owners choose to remove it.

3. Common Problems with the Grid Heater

3.1. Component Failures

A notable issue with the 6.7 cummins grid heater delete is the potential for component failures. As highlighted by Banks Power, bolts within the grid heater can deteriorate and fall into the intake runner, potentially entering cylinder #6. This can cause severe damage to pistons, valves, and cylinder heads, leading to costly repairs or engine failure.

3.2. Electrical Issues

The grid heater can also cause electrical problems. Fault codes like P2609 (indicating issues with the intake air heater system voltage) and P0542 (indicating abnormal input voltage readings) are common. These faults can trigger the check engine light and impact vehicle performance, signaling potential issues with the grid heater or its wiring.

4. Benefits of Deleting the Grid Heater

4.1. Improved Airflow

Deleting the 6.7 Cummins grid heater enhances airflow into the engine by removing obstruction from the intake manifold. This leads to better engine performance and increased power output, as the engine can breathe more freely and operate more efficiently.

4.2. Reduced Maintenance Needs

Removing the grid heater reduces maintenance requirements. Without it, there is less carbon buildup and residue, minimizing the need for frequent cleaning and reducing long-term maintenance costs.

4.3. Enhanced System Reliability

Eliminating the grid heater can improve engine reliability by reducing the risk of electrical and mechanical failures. This is particularly valuable for those who depend on their vehicle for heavy-duty tasks or demanding conditions.

4.4. Increased Modification Potential

With the grid heater removed, you have more space for additional performance upgrades. This includes installing components like the 6.7 Cummins intake horn or a high-performance 6.7 Cummins intake manifold, which can further enhance engine performance and efficiency.
