If you own a 6.7L Cummins diesel truck, chances are you’re all too familiar with the headaches caused by the exhaust gas recirculation (EGR) system. Between clogged EGR coolers, valves sticking open, and reduced power and fuel efficiency, the EGR can spell trouble. This is where an EGR delete kit comes in. By removing the EGR system completely, an EGR delete kit rids you of EGR woes while increasing performance.
In this ultimate guide, we’ll define what the EGR system is, why 6.7 egr delete kits are beneficial, and how to choose the right 6.7 egr delete kit for your truck. We’ll cover installation, the driving experience afterward, common questions, and our recommendations. By the end, you’ll be fully equipped to make an informed decision about deleting your 6.7L EGR.
Things to Consider Before Deleting Your EGR
Before you initiate an EGR delete, there are some important factors to consider. First and foremost, research any legal issues in your state regarding deletes and emissions modifications. An EGR delete could potentially compromise your emissions system and affect if your truck passes testing.
You should also evaluate how a delete might impact your fuel economy and warranty coverage. The engine will run differently without EGR temperature modulation, so you could see lower fuel efficiency. And some manufacturers may not honor your powertrain warranty if they discover an unauthorized delete. Taking time to weigh these considerations will help ensure an EGR delete is the right decision for your truck.

Choosing the Right EGR Delete Kit
With the large variety of kits available online and through aftermarket part suppliers, selecting the appropriate EGR delete kit for your 6.7L Cummins can seem daunting. Kits range from simple plug-and-play options that block or bypass the EGR flow to more involved custom-made solutions.
Plug-and-play systems are convenient but may not be as durable long-term. Custom-fabricated deletes allow for higher-quality components tailored precisely to your engine, but installation can be more complex. It’s important to compare included components, construction materials, proven track records, and warranty coverage between manufacturers.
Consider a kit with stainless steel or aluminum parts for maximum corrosion resistance. Also evaluate online reviews and forum discussions to ensure the kit is a good choice for your desired goals of power, reliability, and driving experience.

Installation Guide
Installing an EGR delete kit requires the right tools and proper technique to ensure a smooth process. This section provides a step-by-step guide to uninstalling the factory EGR hardware and swapping in the new deleted components. We’ll outline the full tool list needed, including socket wrenches, screwdrivers, pliers, and more. Detailed instructions advise removing specific hoses, sensors, and manifolds in sequence.
Helpful photos show exactly where parts connect to aid in the tear-down and rebuild. Tips are also offered, such as using penetrating oil on stubborn fasteners. Once the delete kit is fully installed, the guide describes final checks like verifying all connections are tight and the engine runs as expected. Following the precise steps in this installation guide makes the deletion process straightforward and hassle-free.
Driving Experience After an EGR Delete
So how does a truck feel once that troublesome EGR system is removed? Drivers are impressed by the noticeable surge in engine performance after an EGR delete. Horsepower and torque gains open the door to improved acceleration, towing, and hill-climbing abilities. The turbocharger is less restricted without EGR flow, allowing for quicker spool. Some drivers also comment the engine runs smoother thanks to decreased carbon buildup.
Fuel economy often increases a few MPG highways. However, acceleration may require retraining used to the stock throttle response. Noise levels can rise slightly without the EGR temperature control. Overall though, owners rave about enhanced driving dynamics and never look back after experiencing the liberated power of an EGR-free 6.7L Cummins.
Conclusion
Removing the troublesome EGR system is a popular modification for 6.7L Cummins owners looking to optimize performance and reduce maintenance headaches. This guide provided the information needed to decide if an EGR delete is right for your truck. Considering the factors discussed and choosing a high-quality kit will ensure a smooth installation process. An EGR delete unleashes your engine’s true potential while ridding you of costly EGR repairs down the road. Increased power and reliability are well worth the small investment.
