This 6.7L Cummins EGR delete kit is designed for 2010-2024 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. This upgrade removes the restrictive factory EGR valve and cooler assembly, replacing them with a block-off plate and coolant bypass system.
By eliminating the EGR system, exhaust gases no longer re-enter the intake manifold. This helps improve airflow efficiency, reduce soot buildup, and support more stable engine performance under load. The kit is commonly installed by diesel owners who want improved reliability, better throttle response, and reduced long-term maintenance costs.
The original EGR system recirculates hot exhaust gases back into the intake manifold to meet emissions regulations. While this design is highly effective at controlling emissions, it often introduces particulate matter and heat into the intake manifold.
Over time, this can lead to several problems:
Removing the EGR system will significantly reduce all these problems.
Removing the restrictive EGR system allows exhaust gases to exit the engine more freely. When airflow improves, the engine can operate more efficiently under load.
Drivers may experience:
Acceleration response may improve by up to 0.3 seconds, depending on vehicle setup and driving conditions. Many diesel owners also combine this upgrade with a DPF delete system to further improve airflow and engine efficiency.
Performance results may vary depending on altitude, fuel quality, and other modifications.
Installing a 6.7 Cummins EGR delete kit can significantly reduce long-term maintenance expenses related to the factory emissions system.
Over a 300,000-mile period, potential savings may reach $10,849.28, based on improved fuel efficiency and eliminated service costs.
Fuel Savings
This can translate to:
Eliminate EGR Cleaning Costs
Carbon buildup in the EGR system typically requires cleaning every 20,000 miles.
Typical cost:
Avoid Replacement and Repair Costs
EGR components can eventually fail due to carbon buildup and high temperatures.
Typical repair expenses may include:
Deleting the system removes these failure points and reduces long-term service costs.

SuncentAuto diesel performance components are engineered for durability, airflow efficiency, and precise fitment.
Improved coolant circulation after removing the EGR cooler helps reduce heat buildup around the engine.
Thermal analysis shows possible temperature reductions of:
Lower operating temperatures help reduce stress on sensors, wiring, and hoses.
By improving airflow and reducing restrictions, the engine can deliver more consistent horsepower and torque.
This helps support:
The kit is built using high-strength materials designed for diesel engine environments.
Key construction features include:
The system is designed to withstand temperatures up to 1472°F, ensuring long-term durability.
Installation is straightforward for users with basic mechanical experience.
Estimated installation time: about 1 hour
General installation steps include:
For users performing their own upgrades, following detailed 6.7 Cummins EGR delete instructions can help ensure proper installation and prevent diagnostic errors.
