The term "6.7 Cummins delete kit" refers to modifications made to the 6.7-litre Cummins diesel engine, commonly found in heavy-duty trucks, particularly from the Ram (Dodge) brand. On the other side the term "L5P delete" refers to modifications made to the L5P diesel engine, which General Motors use in heavy-duty trucks, specifically Chevrolet and GMC.
These delete kits typically involve removing or disabling components such as the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR) system, and sometimes the Selective Catalytic Reduction (SCR) system. The purpose of these modifications is often to reduce backpressure, lower intake temperatures, and increase power and fuel efficiency. Custom tuning or programming is often included in these kits to optimize engine performance after removing the emissions-related components.
It's important to emphasize that using delete kits may have legal and environmental consequences, as they can result in increased emissions and violation of emissions regulations. Additionally, using delete kits on vehicles still under warranty may void that warranty.
6.7 Cummins Delete Kit:
The 6.7 Cummins delete kit is a popular diesel engine used in heavy-duty trucks, primarily from Dodge/Ram. A delete kit for this engine typically refers to modifications that disable or remove certain emissions-related components, such as the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR) system, and sometimes the Selective Catalytic Reduction (SCR) system. Truck owners often use these kits to improve performance, fuel efficiency, and longevity, particularly in off-road or racing applications.
Here are the prominent features of the 6.7 Cummins delete kit:
- DPF Delete: Removing the DPF can reduce exhaust backpressure, potentially improving engine efficiency and power output.
- EGR Delete: Disabling the EGR system can prevent the recirculation of exhaust gases, reducing carbon buildup and heat in the intake manifold, which could lead to improved engine performance and reduced maintenance needs.
- SCR Delete: Eliminating the SCR system involves removing the diesel exhaust fluid (DEF) injection and urea tank, which can lead to a simplified and less maintenance-intensive exhaust system.
- Tuning: Many delete kits include custom engine tuning or programming that adjusts fuel delivery and other parameters to optimize performance after removing the emissions components.
- Improved Exhaust Flow: Delete kits may come with aftermarket exhaust systems that offer improved flow and sound compared to the stock system.
5P Delete:
The L5P is a diesel engine produced by General Motors and used in heavy-duty trucks, primarily Chevrolet and GMC. Similar to the 6.7 Cummins, an L5P delete kit typically involves removing or turning off emissions-related components to enhance performance, though specifics may vary.
- DPF Delete: Similar to the Cummins, removing the DPF can improve exhaust flow and overall engine efficiency.
- EGR Delete: Disabling the EGR system can have similar benefits in reducing carbon buildup and intake manifold heat.
- Tuning: Custom tuning may be included to optimize engine performance after removing emissions components. Exhaust System: Aftermarket components can improve exhaust flow and change the exhaust note.
