Discover the benefits of installing an EGR delete kit on your Dodge Cummins. Boost horsepower, improve fuel efficiency, and enhance overall engine performance.

1. What does an EGR delete do on a Cummins?

An EGR delete kit is used to remove or disable the EGR system, bringing more fresh air into the engine and improving combustion efficiency. This is especially true for the 6.7 Cummins EGR Delete Kit and other similar products such as the 6.0 Powerstroke EGR Delete Kit and the Duramax EGR Delete Kit. With an EGR delete, exhaust gas return is reduced, improving engine performance and fuel efficiency.

Detailed effects

  • Reduces Carbon Buildup: The EGR system recirculates some of the exhaust gases back into the intake system, causing carbon buildup. After deleting EGR, the intake system becomes cleaner and the engine runs smoother.
  • Improved combustion efficiency: More fresh air enters the engine, optimising the air-fuel ratio and improving combustion efficiency and power output.
  • Lower engine temperatures: With EGR removal, engine combustion temperatures are reduced, helping to extend engine life.

While there are many advantages to EGR deletion, there are also some disadvantages. Read on to learn about the possible negatives of EGR deletion to help you fully evaluate this modification.

4. Disadvantages of EGR deletion

Whilst EGR delete kits can significantly improve the performance of a diesel engine, there are a number of potential drawbacks and negative impacts, particularly on the environment and the law:

Increased emissions

The main purpose of the EGR system is to reduce nitrogen oxide (NOx) emissions. By removing the EGR system, the vehicle's NOx emissions may increase, which can have a detrimental effect on the environment.

Legal Risks

According to the Environmental Protection Agency (EPA), it is illegal to modify or delete the emission control system. Installation of an EGR Delete Kit may result in legal problems, including fines and vehicle towing.

Warranty Issues

Many vehicle warranty policies specify that any modification to the emission control system will void the warranty. Installing an EGR delete kit may result in increased repair costs.

Wear and tear on engine components

EGR deletion may result in higher combustion temperatures, increasing the rate of wear on internal diesel engine components and shortening the life of the components.

Environmental Responsibility

As a car tuning enthusiast or practitioner, we have a responsibility to protect the environment by ensuring that our vehicle's emissions comply with legal standards.EGR deletion may negatively affect this responsibility.

5. Does an EGR delete increase horsepower?

For many 6.7 Cummins, 6.0 Powerstroke and Duramax owners, one of the notable effects of installing an EGR delete kit is an increase in horsepower. Here is a detailed explanation:

Performance Data

Based on user feedback and real-world test data, there is typically a significant increase in diesel engine horsepower after installing an EGR delete kit. For example, the 6.7 Cummins EGR Delete Kit can increase an engine's horsepower by more than 10 per cent, while the Duramax EGR Delete Kit achieves similar results.

User Experience

Many truck tuner enthusiasts report quicker acceleration response and smoother and more powerful power delivery with EGR deletion. The increase in horsepower is especially noticeable in high-load usage situations, such as towing and off-road driving, making the vehicle better suited to tackle a variety of challenges.


The EGR delete reduces the recirculation of exhaust gases and increases the amount of fresh air entering by optimising the air intake system. This results in fuller combustion and stronger power output, naturally increasing horsepower.

Practical examples

For example, after installing the EGR Delete Kit, an owner of a 6.0 Powerstroke found that the vehicle's hill-climbing ability was dramatically improved, accelerating more quickly and driving more smoothly. This real-world experience has also been verified and recognised by other users.

6. Legality of EGR deletion

Although EGR deletion kits can significantly improve the performance of diesel engines, their legality is somewhat controversial and risky. Below is a detailed analysis of the legality of EGR deletion:

US State Regulations

Regulations for EGR deletion vary from state to state in the United States. Some states may strictly regulate the modification or deletion of emission control systems, and violators of the regulations may face penalties such as fines and vehicle towing. Therefore, it is important to understand local regulations before proceeding with an EGR delete.

EPA Regulations

According to the Environmental Protection Agency (EPA), it is illegal to modify or delete a vehicle's emission control system.The EPA strictly regulates the modification or deletion of emission control systems, and violators may face serious legal consequences, including hefty fines and criminal penalties.

Legal Alternatives

While there are some legal risks associated with EGR deletion, there are some legal alternatives available. For example, there is the option of installing EPA-compliant retrofit components, such as high-performance air filters and exhaust systems, to achieve similar performance gains.

Environmental Responsibility

As car tuning enthusiasts or practitioners, we have a responsibility to protect the environment by ensuring that our vehicles' emissions meet legal standards. Therefore, when considering an EGR delete, you should weigh the performance gains it brings against the possible legal risks and do your bit for the environment.
