The Ultimate Buying Guide: Deleting Your 6.7L Cummins EGR System
The 6.7L Cummins engine is a powerhouse, but its Exhaust Gas Recirculation (EGR) system can sometimes cause headaches. Deleting this system can improve performance and reliability. If you’re looking to install an EGR delete kit, this guide will help you choose the best one.
Key Features to Look For
When shopping for a 6.7L Cummins EGR delete kit, several features make a big difference in how well it works and how long it lasts.
- Complete Kit Contents: A good kit includes everything you need. You want the replacement tubes, necessary gaskets, and all the bolts. Missing parts mean extra trips to the hardware store.
- Check Engine Light (CEL) Prevention: The biggest concern is the Check Engine Light coming on. The best kits include a spacer or plug for the coolant/EGR temperature sensor. This tricks the truck’s computer (ECM) into thinking the EGR system is still working correctly.
- Durability of Components: Look at what replaces the original EGR cooler. Some kits use high-quality stainless steel pipes. Others might use cheaper materials that can rust or fail faster.
Important Materials and Construction
The materials used in the delete kit directly affect its performance and longevity.
Most quality kits use high-grade aluminum or stainless steel for the main block-off plates and replacement tubing. Stainless steel (like 304 grade) resists heat and corrosion very well. Aluminum is lighter and resists rust, but ensure it is thick enough to handle the engine’s heat and vibration.
Gaskets are also crucial. You want gaskets made from high-temperature materials, like layered steel or graphite. Cheap rubber gaskets will quickly burn out, causing leaks and potential damage.
Factors That Improve or Reduce Quality
What makes one kit better than another? It often comes down to design and finish.
Improving Quality:
- Smooth Internal Finish: Kits with smooth, mandrel-bent pipes allow exhaust gases to flow freely. Rough or poorly welded joints can create turbulence and slightly hurt performance.
- Precision Machining: The block-off plates must be cut precisely. If the holes don’t line up perfectly, installation becomes frustrating, and you risk exhaust leaks.
- Powder Coating: A good quality kit often has a durable powder coat finish. This protects the metal from road salt and moisture, keeping your engine bay looking clean.
Reducing Quality:
Cheap kits sometimes skimp on the sensor plugs. If the plug holding the temperature sensor is plastic or uses weak threads, it can vibrate loose. This lets hot exhaust gases hit the sensor directly, which can damage the sensor or cause the ECM to throw codes.
User Experience and Use Cases
Why do people delete the EGR on their 6.7L Cummins? The primary reasons relate to reliability and maintenance.
The factory EGR system often clogs with soot and carbon over time. This clogging restricts exhaust flow and can cause overheating issues, especially when towing heavy loads. Deleting the system removes this weak point.
User Experience: Most users report that after a proper installation (with the necessary ECM tuning, if required by the specific kit), the engine runs slightly cooler under load. Maintenance becomes simpler because you eliminate a major source of soot buildup in the intake manifold. Installation difficulty usually ranges from moderate to difficult, depending on how much surrounding hardware you have to remove. Always follow the manufacturer’s step-by-step instructions carefully.
10 Frequently Asked Questions (FAQ) About 6.7L Cummins EGR Delete Kits
Q: Will deleting the EGR void my engine warranty?
A: Yes, most manufacturers consider modifying emissions equipment a warranty violation. Proceed with this knowledge.
Q: Do I need to reprogram my truck’s computer after installing the kit?
A: Some kits are “plug-and-play” and include a sensor spacer to prevent codes. Others require an aftermarket tuner or custom ECM calibration to run correctly without throwing a Check Engine Light.
Q: Does an EGR delete kit affect my truck’s fuel economy?
A: Many users see a slight improvement in fuel economy. This happens because the engine no longer recirculates hot, inert exhaust gas back into the cylinders.
Q: Is it legal to remove the EGR system?
A: In the United States, removing emissions control devices like the EGR system is illegal for on-road vehicles under the Clean Air Act. These kits are generally sold for “off-road use only.”
Q: How long does the installation usually take?
A: For an experienced DIY mechanic, it might take 3 to 5 hours. Beginners should plan for an entire day, including time for cleaning up the area where the old EGR cooler sat.
Q: Does deleting the EGR hurt my truck’s performance?
A: It usually helps performance, especially at higher RPMs or when towing. It reduces exhaust backpressure and lowers intake temperatures.
Q: What should I do with the coolant lines that were connected to the EGR cooler?
A: The kit should provide proper block-off plugs or caps for the coolant lines. You must seal these completely to prevent coolant leaks.
Q: Can I still pass an emissions test if I delete the EGR?
A: No. If your state requires a tailpipe emissions test, your truck will fail because the system meant to clean the exhaust is missing.
Q: What is the main risk if I install the kit but don’t address the sensor?
A: The Check Engine Light will illuminate immediately. Your truck might also enter “limp mode,” which limits engine power until the issue is fixed.
Q: Are there any downsides to deleting the EGR?
A: Besides the legal issues, some people feel the engine runs slightly louder or smells different because the exhaust gases are not being routed internally.
