Introduction: The Significance and Challenges of EGR Delete
As a 6.7L Cummins owner, you may have experienced issues with engine performance, fuel efficiency, or the high maintenance costs associated with the EGR system. If these issues are familiar, an EGR delete could be a viable solution. The Exhaust Gas Recirculation (EGR) system plays a vital role in reducing nitrogen oxide (NOx) emissions, but it often leads to carbon buildup, reduced engine power, and poor fuel economy.
However, EGR delete modifications can differ significantly based on the model year of your Cummins 6.7L engine. This article will break down the pros and cons of EGR delete based on your vehicle’s model year—2019-2024, 2010-2018, and 2007-2009—so you can make a more informed decision.
1. What is the EGR System? Why Consider Deleting It?
How the EGR System Works
The EGR (Exhaust Gas Recirculation) system works by rerouting a portion of exhaust gases back into the engine’s intake, reducing the formation of nitrogen oxides (NOx). This helps meet emissions standards. However, the process leads to increased carbon deposits, reduced fuel efficiency, and power loss over time, making it a common area for performance upgrades.
Reasons for EGR Deletion
Many owners opt for an EGR delete for the following reasons:
- Power Boost: Deleting the EGR allows for more efficient fuel combustion, leading to improved engine power and throttle response.
- Lower Maintenance Costs: Since the EGR system often leads to carbon buildup and parts failure, removing it can save on repairs and replacements.
- Improved Fuel Economy: More efficient combustion can reduce fuel consumption, especially during long drives or towing.
2. EGR Delete Needs and Challenges for Different Model Years of 6.7L Cummins
2019-2024 6.7L Cummins Owners
For newer 2019 RAM 2500 and 2020 RAM 3500 owners, EGR delete may be more complicated due to stricter emissions regulations. Removing the EGR system could cause the vehicle to fail emissions testing, especially in regions with stringent environmental laws, such as California.
Additionally, the 2019 Cummins EGR Delete may require additional ECU tuning and DEF system adjustments to avoid causing issues with the vehicle’s overall emissions system. Without these modifications, you might experience check engine lights or performance issues.
2010-2018 6.7L Cummins Owners
For owners of 2012 6.7 Cummins or 2015 RAM 3500, the EGR system tends to fail more frequently, especially under heavy loads or towing. Problems like EGR cooler failure or clogging are common, and removing the EGR can result in significant performance gains. Drivers often report improved acceleration and better throttle response after EGR deletion.
2007.5-2009 6.7L Cummins Owners
For owners of 2007 RAM 3500 or 2008 Dodge 6.7 Cummins, EGR systems are relatively older and more prone to issues like carbon buildup. These vehicles tend to have fewer restrictions on emissions regulations, allowing for more freedom to modify the vehicle without immediate legal concerns. EGR deletion in these older models can result in a noticeable increase in power and fuel efficiency.
3. Pros of EGR Delete for 6.7L Cummins
1. Enhanced Engine Performance
When you remove the EGR system on your 6.7L Cummins, the engine no longer recirculates exhaust gases, improving the combustion process's efficiency. This leads to several performance benefits:
- Increased Power: Without the recirculation of exhaust gases, your engine can burn fuel more efficiently, leading to more power at the wheels. Many owners report noticeable improvements in acceleration and overall engine response.
- Better Throttle Response: With no exhaust gases mixing with the fresh intake air, throttle response becomes quicker, making driving feel more engaging and responsive.
For 2019 RAM 2500 or 2012 RAM 3500 owners, an EGR delete can give your engine a performance boost, especially when paired with an EGR delete kit 6.7 Cummins that includes ECU tuning.
2. Improved Fuel Economy
Deleting the EGR system can help your Cummins 6.7L engine run more efficiently. Without the introduction of exhaust gases into the combustion chamber, the engine doesn't have to work as hard to burn fuel, which often results in:
- Reduced Fuel Consumption: Many drivers report improved fuel economy, especially during long-distance drives or when towing heavy loads. The engine uses fuel more effectively, resulting in fewer trips to the gas station.
- More Efficient Power Delivery: The combustion process is more complete, reducing wasted energy and translating to better fuel efficiency, even in demanding conditions.
For example, a 2011 RAM 3500 EGR delete kit can significantly reduce fuel waste in long-haul driving scenarios.
3. Reduced Carbon Buildup
An often overlooked benefit of EGR deletion is the reduction in carbon deposits inside the engine. The EGR system continuously reintroduces exhaust gases back into the engine, leading to carbon buildup over time. These deposits can:
- Clog Engine Components: Affect critical parts like the EGR valve, EGR cooler, and intake system.
- Cause Increased Maintenance Costs: Carbon buildup leads to more frequent maintenance and higher repair costs.
By removing the EGR, you prevent carbon from entering the engine, extending the life of components and reducing maintenance costs.
4. Cons of EGR Delete for 6.7L Cummins
1. Environmental Impact
One of the most significant drawbacks of deleting the EGR system is its impact on the environment. Since EGR deletes prevent exhaust gases from being recirculated into the engine:
- Increased NOx Emissions: NOx gases contribute to air pollution and can cause smog. Without the EGR to lower combustion temperatures, the engine will produce more NOx emissions, which negatively impacts air quality.
- Environmental Regulations: In places with stringent environmental laws like California or under federal regulations in the U.S., removing the EGR system may violate emission standards, leading to possible fines and legal issues. This makes it crucial for owners of vehicles like 2019 RAM 2500 or 2020 Cummins to carefully consider the local laws before making this modification.
2. Legal Concerns
In many regions, the EGR delete is considered illegal because it violates emission regulations. Some areas, such as California, have particularly strict standards set by the California Air Resources Board (CARB), and modifying or deleting emission control systems can lead to:
- Failed Emission Tests: In areas that require smog checks or regular emissions testing, a vehicle with an EGR delete will likely fail.
- Potential Fines: If caught with an illegal modification, owners may face hefty fines or penalties. This is especially true for 2019-2024 6.7L Cummins owners in states with aggressive emissions enforcement.
3. Voiding the Manufacturer’s Warranty
Another con of the EGR delete is that it can void your vehicle’s warranty. Most manufacturers have clear clauses stating that any modification to the emission control system will result in the loss of warranty coverage. For example:
- Engine Warranty Risks: If your 2019 Cummins EGR delete results in engine damage or component failure, you could be left to cover the repair costs yourself, as the manufacturer would no longer be responsible for any defects.
For those looking to keep their warranty intact, an EGR delete kit 6.7 Cummins 2019 might not be the right choice unless you’re prepared to cover potential costs.
