The emission from burning diesel fuels is comparatively greater, and 6.7 Cummins DPF and EGR delete kit has emerged victorious as far as filtering diesel-related particulates is concerned.
Most vehicles, especially those running on diesel engines, must meet the minimum carbon emission threshold.
The Environmental Protection Agency (EPA) has been formed under the Clean Air Act to implement standards that all car manufacturers should follow.
A diesel engine can push the exhaust fumes back into the engine in most cases. When this is no longer possible, one might need to consider an ERG delete kit.
This kit involves retrieving the engine’s ERG (Exhaust Gas Recirculation) valve. It comes as a pre-programmed command that prompts the engine to work without an EGR valve.
You will agree that these two elements are crucial in modern automotive.
6.7 Cummins DPF and EGR Delete Kit: Special Features & Specifications
What is Cummins DPF?
Cummins engines are some of the most powerful engines you can come around. They are designed to meet the need for powerful diesel engines such as trucks, tractors, and other machines.
Most of the Cummins engines comes already fitted with Cummins Diesel Particulate Filter.
That is a special type of filter that has been designed to bar soot accrued from internal combustion from being released into the atmosphere.
Cummins DPF works by literally trapping unburned or partially burned diesel particles and fuel.
The filter is made from a special ceramic material that has been molded into a structure made of small perforations.
Once the unburned exhaust soot settles within the pockets, the engine, at some point, sucks the soot back into the engine for further combustion.
Cummins DPF is highly efficient as it can filter off up to 96 percent of the unburned particles from the engine.
What is EGR Delete Kit?
As the name suggests, EGR (Exhaust Gas Recirculation) is a component found in many modern automotive engines.
It helps control the amount of Nitrogen Oxide (NOx) being released into the atmosphere.
It is made up of a valve that opens to let the exhaust fumes in before forcing them back to the engine for further combustion.
It limits the amount of oxygen reaching the engine, forcing the engine’s trapped NOx fumes to be alternatively used.
EGR delete kit is an operation or procedure that is crucial when the need to cancel the need for an EGR process in the engine.
When the kit is evoked, your engine will expel the exhaust fumes without forcing it back for further combustion.
Therefore, it is not a physical kit but several instructions (software updates) that prompt the engine to abandon the utilization of the EGR valve.

Difference Between 6.7 Cummins DPF And EGR Delete Kit
- The DPF (diesel particulate filter) works by physically trapping the soot that escapes from the engine and then stores it in a compartment with small holes like those found in honeycombs.
When the compartment is full of soot, the exhaust gets congested hence initiating a process regarded as the “regen cycle .”This is a process where the tooth is forced back into the engine’s combustion chamber for complete combustion.
When the burning is complete, the mass of re-burned soot is let out at once. This is not the case in EGR.
- DPF is the replacement, and repair is an expensive encounter, unlike EGR. Additionally, a decision to remove it might jeopardize your engine performance.
If removed, the vehicle horsepower might dwindle. The fuel economy and the life span of an engine can be affected by the removal as well.
- The removal or repair of the DPF can improve the engine performance comparatively. In most cases, using a single DPF for a relatively long time means that more soot will accumulate within the soot trap compartment.
That will, in turn, affect engine efficiency as far as fuel consumption is concerned.
01. To increase the performance of a diesel engine, DPF delete kits become handy. The ultimate results of the DPF delete application will automatically increase the performance of a diesel engine vehicle.
02. On the other hand, the EGR (exhaust gas recirculation) works when an electronic signal prompts it to suck in the exhaust fumes into the engine air intake system. This is different from DPF, where soot from the engine is trapped physically.
03. Unlike the DPF, it sends the exhaust fumes back to the engine in real-time. It does not store or trap any soot for a collective burning and release.
- The EGR delete kits are critical in reducing the amount of soot within the engine combustion chambers. This is because it eliminates the need to re-direct the exhaust fumes back into the engine.
- It reduces the number of exhaust fumes containing soot in the atmosphere but increases soot in the engine.
That is different in DPF, where the soot is trapped, burned again, and released to free up the soot compartment.

Verdict
Deciding on the right type of 6.7 Cummins DPF And EGR Delete Kit can be an uphill task if you are unaware of their fine details.
These two elements are the best for enhancing the performance of diesel engine vehicles. However, their functionality has clear-cut differences.
While DPF physically traps soot particles from the engine, the EGR works by redirecting the exhaust fumes back into the engine.
It is important to understand when respective delete kits are necessary and when they are not.
Overall, identifying the best DPF and ERG kits based on the discussed features and functionality is making critical decisions about improving your diesel engine’s performance.
The 6.7 Cummins DPF and ERG delete kit that tops the list in each category should be considered when deciding how to improve diesel engine performance.
