The Dodge Ram, with its Cummins diesel engine, is proven for great durability, torque, and for lots of heavy-duty applications. Like most modern diesel engines, this one is equipped with an Exhaust Gas Recirculation (EGR) system that reduces emissions by recirculating a portion of exhaust gasses back into the intake manifold. While the EGR system helps meet emissions standards, it can lead to issues such as carbon buildup, reduced efficiency, and maintenance headaches over time.
An EGR delete kit Dodge Ram Cummins diesel has become a popular modification among Dodge Ram Cummins diesel owners looking to enhance performance and reliability. Let’s explore what an EGR delete kit does, its benefits, and important considerations before making this modification.
What Is an EGR Delete Kit?
It simply eliminates or removes the EGR system, which ensures that exhaust gasses are not circulated into the intake. The kit is usually manufactured with block-off plates, hoses, and all the hardware needed to re-route the EGR components or seal them.
Benefits of an EGR Delete Kit for Dodge Ram Cummins Diesel
Improved Performance and Efficiency
The elimination of the EGR system ensures that the engine always gets cool, oxygen-rich air instead of exhaust gasses. All this means better combustion, better response to the throttle, higher power and torque, smoother engine operation, and noticeable performance improvement after the delete; many users report this.
The EGR system allows soot and unburnt hydrocarbons to enter into the intake manifold, and over time, carbon begins to build up. This will clog up the intake, reduce airflow, and negatively impact engine performance. That is completely avoided with an EGR delete to maintain optimal airflow and efficiency.
Lower Engine Temperatures
The hot exhaust gasses which are routed through the EGR system may cause increased engine running temperatures. Removing the EGR ensures that the engine runs cooler, possibly prolonging the life of critical components such as pistons, valves, and turbochargers.
Increased Reliability
The EGR has numerous failure-prone parts, such as the EGR valve and cooler. These parts are pricey to replace or repair. Removing the EGR system thus removes those potential failure points, saving you long-term maintenance costs.
Better Fuel Economy
With enhanced combustion efficiency and a reduction in restrictions, many Dodge Ram Cummins diesel owners report a slight mileage improvement right after having an EGR delete kit installed.
Pre-Installation Considerations
Emissions Compliance
EGR removal is illegal in most countries, as it disregards emissions standards. Driving on public roads fitted with an EGR delete kit may result in fines and may cause the vehicle to fail to pass any mandatory test for emissions. The installation is typically an off-road or competition setup only.
Check Engine Light and ECU Tuning
There’s a possibility that the deletion of the EGR system might cause the check engine light to turn on due to detected changes by the vehicle sensors. Sometimes, the ECU tune is also necessary to readjust or calibrate the engine management system for optimal performance after the delete.
Possible Warranty Void
An EGR delete kit usually voids a vehicle’s warranty. Before installing this modification, review the terms and conditions of your warranty.
Environmental Impact
Whilst deletion of the EGR will improve performance, it will also contribute to increasing NOx emissions, thereby increasing air pollution. This is a trade-off that environmentally savvy drivers should carefully consider.
The Right EGR Delete Kit
When selecting an EGR delete kit for a Dodge Ram Cummins diesel, the kit selected should meet specific engine requirements, such as a 5.9L or 6.7L Cummins. Materials and hardware are of high quality, ensuring durability and ease in installation. Brands like Sinister Diesel and H&S Performance are some of the most reliable when it comes to EGR delete kits that are mostly trusted by the diesel performance community.
Conclusion
An EGR delete kit can be the difference between a night and day difference for the owners of any Dodge Ram Cummins diesel egr deletes kit in terms of performance, reliability, and cost savings in maintenance. However, one must weigh the pros against the cons involving the legal, environmental, and warranty aspects. Once you choose to pursue this enhancement, do it right and include an ECU tune to achieve the highest synergy. The EGR delete kit has been used to help jump the Cummins-powered Ram into top performance while off-roading or on heavy-duty work.
