How to delete EGR 6.7 Cummins

• Author: SPELAB Mechanical Engineer (focusing on car modification for 10 years)

Modifying or deleting the EGR (Exhaust Gas Recirculation) system on a vehicle is typically considered an aftermarket modification.

About the EGR delete kit

An EGR delete kit is designed to assist in removing or bypassing the EGR system of a vehicle. It typically includes various components and hardware necessary for modifying the engine's EGR system.

EGR delete kits can vary depending on the specific vehicle make and model, as well as the desired level of modification. Some common components found in an EGR delete kit may include:

EGR block-off plates: These plates are designed to cover or block the exhaust and intake ports where the EGR system is connected. They help prevent the flow of exhaust gases into the intake manifold.

EGR delete pipe: This is a pipe that replaces the EGR cooler, allowing for the removal of the cooler and rerouting of the exhaust gases.

EGR delete tuning software: Some kits may include software or tuners that modify the engine control unit (ECU) to prevent fault codes and potential limp mode issues that can occur after deleting the EGR system. This software adjusts the engine management parameters to account for the deleted or bypassed EGR system.

Hardware and gaskets: EGR delete kit often include various bolts, clamps, and gaskets required for the installation. These ensure proper sealing and secure mounting of the modified components.

Documentation and instructions: A good EGR delete kit should provide detailed instructions or documentation to guide you through the installation process. It's essential to follow these instructions carefully to ensure a proper and safe installation.

6.7 Cummins egr delete kit

when it comes to EGR removal kits for 6.7 Cummins engines, different manufacturers offer a wide range of options. It is important to choose a reputable brand that offers quality and reliable products. First, you need to identify the accessories, which include the following:

6.7 cummins egr delete kit Blocking Plates or Blocking Tubes: These parts are designed to block or replace the EGR cooler, ensuring that exhaust gases are no longer recirculated back into the intake system.

Hardware and Gaskets: The kit should include all necessary hardware such as bolts, clamps, and gaskets to ensure proper installation and sealing of the retrofit components.

Here are the general steps involved in deleting the EGR system:

Disconnect the battery: Begin by disconnecting the negative terminal of the vehicle's battery to prevent any accidental electrical issues during the modification process.

Remove EGR components: Locate the EGR system components, which typically include the EGR valve, EGR cooler, and associated piping. Disconnect and remove these components from the engine bay.

Block exhaust ports: Since the EGR system recirculates exhaust gases, you'll need to block off the exhaust ports where the EGR system was connected. This can be done using block-off plates or by welding the ports shut. Ensure that the block-off plates or welds are properly sealed to prevent any exhaust leaks.

Modify the intake system: To prevent the intake manifold from receiving recirculated exhaust gases, you may need to modify or replace the intake system. This could involve removing any EGR-related components, such as the EGR cooler, and rerouting or blocking off the associated intake ports.

Update engine control unit (ECU) software: Deleting the EGR system will trigger fault codes and potentially cause the vehicle to go into limp mode. To prevent this, you may need to update the ECU software or install a specialized EGR delete tuner. This will modify the engine management system to bypass or ignore the EGR-related sensors and signals.

Optional: Install a DPF delete kit (if applicable): Deleting the EGR system may also require removing or modifying the DPF (Diesel Particulate Filter) system, depending on your local regulations and vehicle setup. This step is optional and highly dependent on the specific requirements of your region.

These are just some brief introductions, to go deeper you will be able to find Spelab for a detailed tutorial.

Expansion

In addition to the EGR delete kit, there are Dpf delete pipes that can improve the performance of the car.

Dpf delete pipe

A DPF (Diesel Particulate Filter) delete pipe is designed to replace or bypass the DPF system in a diesel vehicle. The DPF is responsible for capturing and reducing particulate matter emissions from the exhaust gases of a diesel engine. However, some vehicle owners may opt to remove the DPF for various reasons, such as increased performance or addressing potential maintenance issues.

DPF delete pipes generally replace the DPF section of the exhaust system with a straight pipe. The delete pipe is designed to fit in place of the original DPF, allowing for the free flow of exhaust gases without passing through the filter.

When considering a dpf delete pipe, here are some important factors to keep in mind:

Quality and compatibility: Choose a reputable brand that offers a high-quality delete pipe specifically designed for your vehicle's make, model, and engine. Ensure that the pipe is compatible with your exhaust system and has the necessary fittings for a proper installation.
