Are you tired of dealing with exhaust gas recirculation (EGR) issues in your vehicle? If so, it may be time to consider using a 6.7 EGR delete kit. In this article, we will explore the pros and cons of utilizing such a kit, allowing you to make an informed decision for your vehicle’s needs.

What is an EGR Delete Kit?

An EGR delete kit is a product designed to remove or bypass the EGR system in a vehicle. The EGR system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine for combustion. However, over time, carbon deposits can build up in the EGR system, leading to reduced performance, increased fuel consumption, and potential engine damage.

The Pros of Using a 6.7 EGR Delete Kit

  1. Increased Performance: One of the main benefits of using a 6.7 EGR delete kit is the potential for increased performance. By removing the EGR system, you can eliminate the risk of clogged or stuck valves, allowing for improved airflow and combustion. This can result in increased horsepower, torque, and overall engine efficiency.
  2. Improved Fuel Economy: Without the EGR system in place, your engine can operate more efficiently, which may lead to improved fuel economy. With better combustion and reduced carbon buildup, you can expect to see a decrease in fuel consumption, saving you money at the pump.
  3. Extended Engine Life: The EGR system can contribute to the buildup of carbon deposits in the engine, potentially causing damage over time. By removing the EGR system with a delete kit, you can reduce the risk of carbon buildup and extend the life of your engine.
  4. Reduced Maintenance: EGR-related issues can be costly to repair, requiring frequent cleaning or even replacement of components. By eliminating the EGR system, you can reduce the need for ongoing maintenance and decrease the likelihood of future breakdowns or expensive repairs.
  5. Simplified Troubleshooting: With the EGR system removed, troubleshooting engine issues can become easier. Without the added complexity of the EGR system, mechanics and DIY enthusiasts can focus on other potential causes of problems, leading to more accurate diagnostics and efficient repairs.

The Cons of Using a 6.7 EGR Delete Kit

  1. Increased Emissions: It is important to note that removing the EGR system with a delete kit can lead to increased emissions. The EGR system plays a crucial role in reducing nitrogen oxide (NOx) emissions, which contribute to air pollution and smog. Removing this system may result in higher emissions, potentially impacting the environment.
  2. Potential Legal Issues: In some regions, using an EGR delete kit may be illegal. Regulations regarding emissions control vary from country to country and even within different regions. Before installing a delete kit, it is essential to research and understand the laws and regulations in your area to avoid any potential legal issues.
  3. Warranty Implications: Using a 6.7 EGR delete kit might void your vehicle’s warranty. Manufacturers typically do not endorse tampering with emissions control systems, and modifying your EGR system can result in the invalidation of warranty coverage. It is crucial to consider the potential warranty implications before installing a delete kit.
  4. Engine Tuning Required: In most cases, removing the EGR system with a delete kit requires engine tuning or reprogramming. This additional step may involve additional costs and time spent to ensure proper engine performance and reliability. It is essential to factor in these considerations when making your decision.


If you’re tired of dealing with EGR system-related hassles in your vehicle, a 6.7 EGR delete kit may provide a solution. By removing the EGR system, you can potentially experience increased performance, improved fuel economy, extended engine life, and reduced maintenance. However, it’s important to weigh these benefits against the potential drawbacks, such as increased emissions, legal issues, warranty implications, and the need for engine tuning. Ultimately, it is crucial to assess your vehicle’s specific needs, local regulations, and warranty coverage before deciding to use a 6.7 EGR delete kit.
