EGR deletion is a modification that has gained traction among diesel vehicle enthusiasts looking to enhance engine performance. By removing the exhaust gas recirculation (EGR) system, this approach aims to optimize power output and fuel efficiency. Understanding the mechanics behind an EGR delete, as well as its potential benefits and drawbacks, is essential for anyone considering this modification.
The EGR system primarily functions to recirculate a portion of exhaust gases back into the engine intake, which can help lower emissions and improve fuel economy. However, this process may introduce challenges such as decreased power and increased engine wear. Evaluating the advantages, such as increased performance and potentially higher fuel efficiency, alongside the disadvantages, including possible engine complications, will provide a clearer picture for those contemplating an EGR delete.

For the Dodge Ram 2500 and 3500 models from 2013 to 2024 equipped with the 6.7 Cummins Diesel engine, performance enhancements can be achieved through modifications such as the EGR (Exhaust Gas Recirculation) delete. The removal of the EGR system may lead to improved airflow into the engine, enhancing acceleration and overall performance.
Benefits of EGR Deletion
- Increased Airflow: By eliminating the EGR system, cooler air enters the combustion chamber, potentially resulting in better combustion efficiency.
- Improved Turbo Response: Removing restrictions in the exhaust flow can allow for quicker turbo spool-up, which translates to more immediate power delivery.
- Reduced Engine Temperatures: The absence of exhaust gases helps in lowering coolant temperatures, contributing to better engine reliability.
Considerations Before Deletion
While the benefits may seem enticing, it is crucial to acknowledge the legal implications associated with modifying emissions systems:
- Legal Compliance: Removal of factory-installed emissions controls is illegal in many jurisdictions, regardless of local testing protocols.
- Potential for Increased Maintenance: The EGR system is known to clog over time, especially in high-mileage vehicles. By deleting the system, owners might save on long-term repairs associated with those blockages.
Available Kits
Those considering an EGR delete for their Cummins engine should be aware of the various kits available:
- Complete Delete Kit: Comprehensive packages typically include EGT sensor harness, threaded fittings, and wiring harness protectors.
- Performance Upgrades: Some kits boast enhancements that can increase power and improve engine reliability by facilitating better coolant flow and reducing the intake of sooty air.
In summary, while EGR deletes present performance benefits, they come with significant legal and practical considerations that owners should carefully evaluate before proceeding with modifications.
FAQs
What is an EGR Delete?
An EGR delete involves removing the Exhaust Gas Recirculation (EGR) system from a vehicle. This modification is usually performed using an aftermarket kit designed for this purpose.
What are the benefits of an EGR Delete?
- Increased Power: By eliminating the EGR system, the engine can operate more efficiently, often leading to improved horsepower.
- Better Fuel Efficiency: Many users report that their vehicle’s fuel economy improves after the EGR system is removed.
- Reduced Maintenance Issues: Without the EGR, there may be fewer problems related to carbon buildup in the engine.
Are there any drawbacks to an EGR Delete?
- Legal Issues: In some regions, such as the United States, removing the EGR can violate emissions laws, potentially resulting in fines or penalties.
- Engine Knocking: In certain cases, removing the EGR system might cause engine knocking or other performance issues.
- Warning Lights: The vehicle’s onboard computer may trigger warning lights due to the absence of the EGR system.
Is an EGR Delete advisable for all vehicles?
No, the decision to perform an EGR delete primarily depends on the vehicle’s intended use. It might be more beneficial for off-road or heavy-duty applications than for standard road use.
What is involved in performing an EGR Delete?
The process typically requires the use of an aftermarket EGR delete kit, which usually includes all necessary components and detailed instructions for installation.
