Deciding to pick up a 2018 ram 2500 egr delete kit is usually the first step toward making your Cummins actually run the way it was meant to from the factory. If you've spent any time behind the wheel of a late-model diesel, you know exactly what I'm talking about. These trucks are absolute powerhouses, but they're also weighed down by a lot of "breathing" issues. It's like trying to run a marathon while breathing through a dirty sock.
The Exhaust Gas Recirculation (EGR) system was designed with good intentions—mostly to lower nitrogen oxide emissions—but for the average truck owner, it's often a source of headaches. Between the clogged valves and the layers of soot building up in your intake, it doesn't take long before your 6.7L Cummins starts feeling a bit sluggish. That's why so many people end up looking for a way to just get rid of it entirely.
What's the Deal with EGR Anyway?
To understand why a 2018 ram 2500 egr delete kit is such a popular mod, you have to look at what the system actually does. Essentially, the EGR takes a portion of your hot, dirty exhaust gases and pipes them back into the intake manifold. The idea is to lower combustion temperatures, which reduces certain pollutants.
The problem? Exhaust is inherently dirty. It's full of soot and carbon. When you mix that "soot soup" with the oily vapors coming from your crankcase, you get a thick, nasty sludge that coats your internals. Over time, this buildup restricts airflow, kills your fuel economy, and can even lead to stuck valves. If you've ever seen a high-mileage intake manifold that hasn't been deleted, it's a pretty gross sight—it looks like the inside of a chimney.
Why 2018 Owners are Making the Switch
By the time 2018 rolled around, Ram had the 6.7L Cummins pretty well figured out, but the emissions equipment remained the "Achilles' heel" of the platform. Owners often report that around the 50,000 to 70,000-mile mark, things start getting finicky. You might get a "Perform Service" message on the dash, or the truck might start feeling a little jerky under light acceleration.
Installing a 2018 ram 2500 egr delete kit changes the game. By removing the cooler and the valve, you're ensuring that only clean, cool air enters your engine. This leads to a few immediate changes that you'll notice almost the second you pull out of the driveway.
First off, the throttle response gets way crisper. Because the engine isn't trying to burn its own trash, the combustion process is much cleaner and more efficient. Secondly, your Exhaust Gas Temperatures (EGTs) will usually drop. Lower EGTs are a huge win for the longevity of your turbo and your head gasket. Heat is the enemy of any engine, especially a turbocharged diesel.
What's Actually Inside the Kit?
When you buy a 2018 ram 2500 egr delete kit, you aren't just getting one part. It's a collection of hardware designed to seal off the holes left behind when you pull the factory components off. Usually, you'll find a couple of heavy-duty block-off plates made from steel or aluminum. These bolt onto the exhaust manifold and the intake.
You'll also get a coolant bypass hose. Since the factory EGR cooler has coolant running through it to lower the temp of those exhaust gases, you can't just rip it out and leave the lines dangling. The bypass hose keeps the coolant flowing through the rest of your engine's cooling system so you don't end up with hotspots or leaks. Most kits also include all the necessary gaskets, nuts, and bolts so you aren't running to the hardware store in the middle of the job.
The Tuning Side of Things
Here is the part where people sometimes get tripped up: you can't just bolt on a 2018 ram 2500 egr delete kit and call it a day. If you do that, your truck's computer (the ECM) is going to freak out. It'll see that the EGR valve isn't responding and that the airflow readings are "wrong" according to its factory programming. This will instantly trigger a limp mode, and your truck will have about as much power as a golf cart.
To make a delete work, you need a tuner. Software like EFI Live or EZ Lynk is the industry standard here. The tuner tells the truck's computer to ignore the missing EGR components. It basically "turns off" those sensors so the truck runs happily without them.
The cool part is that while you're tuning the truck for the delete, you can also add a little bit of extra horsepower. Even a "street" tune can add 50 to 100 horsepower while still being safe for a daily driver. It's like waking up a sleeping giant.
Better Fuel Economy and Less Maintenance
Let's talk about the wallet for a second. We all know diesel isn't exactly cheap these days. One of the biggest complaints with EGR-equipped trucks is the fuel mileage. Because the engine is essentially "choking," it has to work harder to maintain speed.
After installing a 2018 ram 2500 egr delete kit and a proper tune, most guys see an immediate jump in MPG. It's not uncommon to gain 2 to 4 miles per gallon on the highway. If you drive a lot of miles for work or towing, those savings add up fast. In a year or two, the kit often pays for itself just in fuel savings alone.
Then there's the maintenance aspect. EGR valves are notorious for failing or getting stuck. Replacing one at the dealership isn't cheap. By removing the system, you're removing a part that is guaranteed to fail eventually. It's one less thing to worry about when you're out on a long road trip or hauling a heavy trailer through the mountains.
Is It a Difficult DIY Project?
If you're someone who likes to turn their own wrenches, installing a 2018 ram 2500 egr delete kit is definitely doable in a Saturday afternoon. It doesn't require any crazy specialized tools, but you will want a good set of sockets, some extensions, and maybe a bit of patience for those hard-to-reach bolts near the firewall.
The trickiest part is usually getting the factory EGR cooler out. It's a bit of a bulky unit, and the bolts can be stubborn if they've been heat-cycled a thousand times. A bit of penetrating oil the night before goes a long way. Once the old stuff is out, bolting the delete plates on is pretty straightforward. Just make sure your gaskets are seated correctly so you don't end up with an exhaust leak.
A Quick Word on the "Off-Road" Label
You'll see it on every website selling these parts: "For Off-Road Use Only." It's important to remember that removing emissions equipment is technically a violation of federal law if you're driving on public roads. Depending on where you live, you might have tailpipe inspections or visual checks that would make a delete a no-go.
However, for guys who use their trucks on the farm, for competition, or in areas without strict testing, the 2018 ram 2500 egr delete kit remains the go-to modification. It's all about weighing the pros and cons for your specific situation.
Wrapping It Up
At the end of the day, your 2018 Ram 2500 is a massive investment. You want it to last as long as possible, and you want it to be reliable. For a lot of owners, the EGR system feels like a ticking time bomb for the engine's health.
By opting for a 2018 ram 2500 egr delete kit, you're choosing to let your Cummins engine breathe the way it was engineered to. You get better throttle response, improved fuel economy, and the peace of mind that comes with knowing you won't have a soot-clogged intake manifold ten thousand miles down the road. It's one of those mods that once you do it, you'll probably wonder why you waited so long to pull the trigger. Just make sure you get a quality kit and a solid tune, and your truck will thank you for years to come.
