Boost Your Diesel Engine: Cummins Delete Kit and EGR Delete Kit for 6.7 Cummins

Introduction to the Power of Cummins Diesel Engines

Diesel engines have long been admired for their strength, torque, and longevity. For owners of the iconic 6.7L Cummins engine, performance and reliability are essential. Whether you are hauling heavy loads, pushing through off-road terrains, or simply looking for more efficiency, proper maintenance and smart upgrades can make a massive difference.

Among the most impactful upgrades are the Cummins delete kit and EGR delete kit designed specifically for 6.7 Cummins engines. These aftermarket modifications can boost performance, increase fuel economy, and reduce long-term maintenance issues. In this comprehensive guide, we will explore how these kits work, the benefits they provide, and how to choose the right kit for your Cummins-powered truck.

Understanding the 6.7L Cummins Platform

The 6.7L Cummins turbo diesel engine has powered Ram trucks since the 2007.5 model year and has become one of the most respected names in diesel performance. It is used in Ram 2500, 3500, 4500, and 5500 trucks, delivering immense torque and superior towing capabilities. However, like all modern diesel engines, it comes equipped with strict emissions equipment that can restrict performance.

This is where delete kits come into play.

What Is a Cummins Delete Kit?

A Cummins delete kit is an aftermarket upgrade designed to remove or bypass factory emissions systems. These kits usually target the following components:

• DPF (Diesel Particulate Filter)
• EGR (Exhaust Gas Recirculation)
• DEF (Diesel Exhaust Fluid)
• SCR (Selective Catalytic Reduction)

The purpose of these components is to reduce tailpipe emissions, but they often come at the cost of performance, fuel economy, and engine longevity. A delete kit removes these restrictions, allowing your Cummins engine to breathe and perform as it was originally designed to do.

Benefits of a 6.7 Cummins Delete Kit

Installing a Cummins delete kit offers several compelling benefits:

Increased Horsepower and Torque: Removing emissions restrictions allows the engine to generate more power.

Better Fuel Economy: Many users report a two to five miles-per-gallon improvement.

Improved Throttle Response: The engine responds faster and more smoothly under load.

Lower EGTs (Exhaust Gas Temperatures): This helps protect your turbocharger and engine internals.

Reduced Maintenance Costs: You no longer have to deal with DPF regeneration cycles, DEF refills, or EGR valve failures.

For those who use their trucks for heavy towing, off-road driving, or competitive performance, these benefits can translate into more reliable and consistent operation.

What Is an EGR Delete Kit for 6.7 Cummins?

The EGR (Exhaust Gas Recirculation) system is designed to recirculate a portion of your exhaust gas back into the combustion chamber to reduce nitrogen oxide (NOx) emissions. While this process is effective for lowering emissions, it can lead to several problems such as:

Carbon buildup in the intake manifold

Reduced engine efficiency

Higher engine temperatures

An EGR delete kit for the 6.7 Cummins eliminates this system entirely. The kit typically includes:

EGR block-off plates

Coolant reroute hoses

Intake plugs

Installation hardware

Advantages of Installing an EGR Delete Kit

Installing an EGR delete kit offers several significant advantages:

• Reduced Carbon Deposits: This keeps the intake valves and manifold cleaner for longer.
• Improved Reliability: The kit removes a common failure point in modern diesel engines.
• Lower Exhaust Temperatures: This results in less heat stress on critical engine components.
• Better Fuel Efficiency: The system optimizes combustion by using only fresh air.
• Boosted Performance: The engine runs smoother and more efficiently, especially under load.

Deleting the EGR system is one of the most cost-effective methods to improve both performance and durability in your 6.7 Cummins engine.

How to Choose the Right Cummins Delete Kit?

When selecting a delete kit for your 6.7 Cummins, consider the following factors:

Model Year Compatibility: Kits are typically grouped into 2007.5–2012, 2013–2018, and 2019–2022 versions.

Kit Components: Ensure the kit includes an EGR delete, DPF delete pipe, tuning software, and coolant reroute hardware.

Material Quality: Look for components made from stainless steel and CNC-machined aluminum.

Tuner Compatibility: Tuners such as EFI Live, MM3, or RaceMe are often required to prevent check engine lights and optimize performance.

Reading customer reviews and researching reputable brands is essential. Websites like DynoVoxParts.com specialize in high-quality Cummins delete kits that are tailored to your specific truck model.

Is It Legal to Use a Delete Kit?

Using a delete kit is legal only for off-road and competition use. These modifications are not street-legal in many U.S. states due to EPA regulations. Violations can lead to significant fines. Always check your local and federal laws before installing any emissions delete system.

Installation Guide: EGR and DPF Delete on a 6.7 Cummins

If you are confident in your mechanical skills, you can install most delete kits at home. Here is a simplified step-by-step process:

1. Disconnect the battery and drain the engine coolant.
2. Remove the EGR valve, cooler, and pipes using the instructions provided with your kit.
3. Install block-off plates and the coolant bypass components.
4. Replace the DPF/SCR exhaust section with a high-flow race pipe.
5. Install tuner software and upload the appropriate custom tune.
6. Double-check all fittings, refill the coolant system, and reconnect the battery.

Professional installation is recommended if you are unfamiliar with diesel engine systems or lack the necessary tools.

Conclusion: Is a Cummins Delete Kit Right for You?

If you are serious about maximizing performance, improving towing capacity, or increasing off-road capability, installing a Cummins delete kit and an EGR delete kit for your 6.7 Cummins engine can deliver real, measurable improvements. You will benefit from:

• More horsepower and torque
• Cleaner engine internals
• Lower long-term operating costs
• A better overall driving experience

However, it is crucial to remember that these modifications are intended for off-road or competition use only. Always ensure that you are compliant with local and federal emissions laws before proceeding with installation.
