6.7 Cummins Performance: How to Install an EGR Delete Kit
You love your Cummins diesel truck. That 6.7-liter engine has power for days and the potential for so much more. But you’ve noticed the dreaded “check engine” light comes on from time to time, often triggered by issues with the exhaust gas recirculation or EGR system. The EGR routes exhaust back into the engine to reduce emissions, but it also reduces performance and engine efficiency. An EGR delete kit is an easy solution to eliminate that system once and for all. Installing an EGR delete kit on your Cummins will free up lost horsepower and torque, improve throttle response, reduce engine heat, and prevent future EGR-related check engine lights. If you’re ready to unleash the full potential of your 6.7 Cummins, here’s how to install an EGR delete kit in just a couple hours.
What Is an EGR Delete Kit for the 6.7 Cummins Engine?
An EGR delete kit removes your 6.7 cummins egr delete kit engine’s exhaust gas recirculation system. EGR reduces nitrogen oxide emissions by recirculating some exhaust gas back into the engine. Removing it improves performance, fuel economy, and reliability.
Installing an EGR delete kit on your Cummins involves removing the EGR valve, cooler, and associated plumbing. First, locate the EGR valve—it’s the component with hoses connecting the exhaust manifold to your intake. Disconnect the inlet and outlet hoses. Then unbolt the EGR valve and cooler from the engine.
With the hardware removed, you’ll install a blanking plate to cover the opening in your intake manifold where the EGR valve was mounted. The kit will include a pipe to connect your exhaust manifold to the turbocharger. Install the pipe, connect all remaining hoses, and you’re done.
An EGR delete kit can increase horsepower and torque, improve throttle response, and boost fuel economy by up to 2 MPG. Your engine will run cooler without the added exhaust heat and last longer without the EGR system to clog or fail.
If emissions compliance isn’t an issue in your area, an EGR delete kit is one of the best upgrades you can make to a 6.7 Cummins. More power, better fuel efficiency, lower EGTs, and higher reliability—what more could you ask for? Do it right with a quality EGR delete kit and that Cummins will be purring like a kitten in no time
Benefits of Installing an EGR Delete on Your 6.7L Cummins
One of the best upgrades you can make to your 6.7L Cummins is installing an EGR delete kit. Here are a few of the major benefits you’ll notice:
Improved Engine Performance
Removing the EGR valve and cooler eliminates the circulation of exhaust gasses, allowing your engine to breathe better. This results in more efficient combustion, increased throttle response, and higher power output. Many owners report gains of 50-100 horsepower.
Extended Engine Life
Exhaust gasses contain contaminants like soot, unburnt fuel, and water vapor which can build up in your intake system and EGR components, reducing their effectiveness. By deleting the EGR, you prevent this buildup and reduce strain on the engine, potentially adding years of life to your Cummins.
Reduced Maintenance
With no EGR valve or cooler, there are fewer parts to maintain or replace. You’ll no longer need to clean the EGR valve or cooler, saving you time and money.
Improved Fuel Economy
A properly functioning EGR delete kit can improve your fuel efficiency by up to 1-2 MPG. The cleaner combustion and reduced soot buildup allow your engine to make the most of each drop of fuel.
If you’re looking for more power, improved reliability, and lower costs of ownership from your 6.7L Cummins, an EGR delete kit is one of the best modifications you can make. Your engine will thank you, and you’ll feel the difference every time you step on the throttle.
Step-by-Step Guide to Installing an EGR Delete Kit on a 6.7 Cummins
To install an EGR delete kit on your 6.7 Cummins, follow these steps:
Remove the EGR Valve
The EGR valve is located on the driver’s side of the engine. Loosen the hose clamps connecting the valve to disconnect all hoses. Unbolt the EGR valve from the engine and intake manifold, then remove it. Clean the mounting surfaces thoroughly.
Install the EGR Delete Plate
The delete plate blocks off the EGR passageways. Place the gasket on the intake manifold, then position the delete plate over it. Install the provided bolts and tighten in a star or criss-cross pattern. Torque the bolts to the recommended specification, typically around 15 to 20 foot-pounds.
Replace the Intake Elbow
Remove your stock intake elbow to access the EGR passage behind it. Install the new intake elbow included in your kit, ensuring the gasket is properly aligned before tightening the clamps. Tighten the clamps to the recommended torque, around 5 to 10 foot-pounds.
Optional: Install Coolant Lines
If your kit includes coolant lines, remove the lines connected to the EGR cooler. Install the provided lines in their place, tightening securely with hose clamps. Refill the coolant system and check for any leaks.
Optional: Install an EGT Probe
An exhaust gas temperature (EGT) probe allows you to monitor exhaust temperatures, which may increase after deleting the EGR system. Install the probe in your exhaust manifold or turbocharger downpipe according to the instructions. Route the wiring to your gage panel inside the cab.
With the EGR delete kit installed, your 6.7 Cummins will breathe better and run more efficiently. Be sure to re-tune your vehicle’s computer to disable any EGR-related codes for the best performance. Enjoy the improved throttle response and power!
Conclusion
So there you have it, with an EGR delete kit installed on your 6.7 Cummins, you’ll be feeling the power and performance boost right away. No more choking, stalling, or limp mode to deal with. Your engine can finally breathe easy and do what it was built to do. Make sure to get quality components, follow the directions carefully, and take your time with the install. Once it’s done though, you’ll be glad you made the upgrade. Crank it up and listen to that turbo really spool – your Cummins will sound meaner and drive better than it ever has. Time to get out on the open road and see what your diesel can really do! An EGR delete is one of the best mods you can make.
