How to Install a 6.7 Cummins EGR Delete Kit: Step-by-Step Guide 2026

If you're driving a Ram truck with a 6.7 Cummins engine, understanding how to maintain and upgrade it is key to maximizing performance and longevity. One popular modification is installing a 6.7 Cummins EGR delete kit. This guide will walk you through what an EGR delete kit is, whether you should delete your EGR system, how to install the kit, and weigh the costs and benefits so you can decide if this upgrade fits your needs.

What Is a 6.7 Cummins EGR Delete Kit and Should You Delete It?

A 6.7 Cummins EGR delete kit is designed to remove the Exhaust Gas Recirculation (EGR) system, which recirculates exhaust gases back into the intake to reduce emissions. Removing it often improves airflow and reduces soot buildup inside the engine, offering potential performance boosts. However, deleting your EGR can increase emissions, possibly causing legal and warranty issues. While many diesel truck owners see gains in reliability and cleaner operation, you should consider state regulations and the impact on your vehicle’s emissions compliance before proceeding.

Step-by-Step Instructions to Install Your 6.7 Cummins EGR Delete Kit

Before starting, gather essential tools such as wrenches, sockets, screwdrivers, and safety gear like gloves and eye protection. Prepare your workspace by ensuring the engine is cool and the vehicle is on level ground. Begin by disconnecting the battery, then carefully remove stock EGR components including valves and cooler lines. Install the delete kit’s heat-resistant components and bolt-on brackets using the provided hardware. Pay close attention to sensor relocation and coolant reroute instructions to maintain engine safety and performance. After mechanical installation, update or flash your vehicle’s software if needed to accommodate the delete, ensuring smoke-free performance tunes with OE-level connectivity.

Costs, Benefits, and Is an EGR Delete Worth It?

The cost of a 6.7 Cummins EGR delete kit can vary from a few hundred dollars for the hardware alone, up to higher prices if you include professional installation and tuning. Fuel efficiency often improves slightly, while power and throttle response benefit notably due to reduced restrictions. Maintenance becomes easier with less soot buildup, potentially increasing engine longevity. Many diesel enthusiasts consider EGR deletion part of the “holy grail” of Cummins mods because it enhances performance and reliability when done correctly. Ultimately, whether it's worth it depends on your local laws, your vehicle’s intended use, and your tolerance for warranty risks.
