What are 6.7 Powerstroke DPF and EGR Delete Benefits In 2023?

6.7 Powerstroke DPF and EGR delete benefits can be summarized into better performance, increase in fuel economy, and horsepower. But there’s more to it than just a couple of advantages.

Here, we’ve done our best to detail everything you need to know about a DPF and EGR delete. From benefits, disadvantages, and so much more!

That being said, here’s a quick introduction to emission systems to prepare you for exploring further details about these restrictive systems.


What Does it Mean to Delete Your Emission System?

Over the years, the government has taken particular actions against emissions produced by your vehicle’s engine.

They’ve realized that these toxic air pollutants emitted by your car, can be catastrophic for both human beings and the environment.

Thus, emission systems have become mandatory in many countries.

Simply put, the emission system reduces the emission made by your engine, which otherwise would end up being released into the environment.

Unfortunately, the technology just isn’t there yet.

For instance, the emission system can decrease your engine’s performance and fuel economy. As a result, movements against emission systems have increased over the years.

As you would expect, to delete your emission system simply means to take off the DPF, EGR, and SCR.

By removing these three parts of your vehicle, you’d get rid of all these annoying features, which decrease your overall performance and sometimes harm the engine.

Is it Legal to Delete DPF & EGR?

Yes, it is illegal to install a 6.7 Powerstroke DPF and EGR delete kit. Removing anything required by the government is illegal and could get you in trouble.

By removing them, you’re creating more emissions, which is precisely what the government is trying to avoid.

You can go through a police checkpoint, and the moment you pull up, they have the right to inspect your vehicle.

And if they notice that you removed the EGR or DPF, you’ll get in trouble.

However, bear in mind that they are prohibited for street racing, but legal for off-road trucks.

But as always, your country or state might have different laws regarding emission systems. Therefore, check your federal laws for more information about this topic.

Can I Sell A Deleted Truck?

If there’s a question we’ve seen a lot is whether you’re legally allowed to sell your deleted truck. The shower answer is no.

You cannot sell your truck after you’ve deleted the emission system. As we said before, it is illegal to delete the DPF and EGR.

Therefore, if you ever try to sell or trade your vehicle in, you’ll most likely have some legal issues.

Even if you take the truck to an auction, cops will most likely show up to make sure there’s nothing fishy going on.

They will inspect all the vehicles going up for sale, and the moment they find out you modified the emission system, you’ll face a huge bill.

9 Reasons Why You Should Delete your DPF & EGR

You probably know somebody who knows a guy who has deleted the DPF & EGR emission system.

But is it worth the money and effort? Well, here are some 6.7 Powerstroke DPF and EGR delete benefits:

It’s Better for the Engine

The whole idea behind the EGR is to route some of the engine’s exhaust gases back into your engine’s cylinders.

This is a nice feature to have as it helps the engine with waste gases and reduces toxic air pollutants like nitric oxide.

This sounds great on paper. However, it’s had the opposite result.

Thanks to the cooler combustion caused by the EGR, your gas mileage and power will decrease.

And to make things even worse, it can also clog up parts of your cylinder. You can probably see how the last one would end.

Deleting the EGR will increase your gas mileage and power. Finally, it’ll also reduce contamination that could harm your engine.

Can Save You Some Money

Hold up. We know that deleting your emission system is pretty expensive. However, the DPF system is outrageously overpriced if it ever stops working.

For instance, changing out the DPF can cost over $4,000. That’s just outrageous for such a problematic system.

By getting rid of the emission system, you would avoid large bills in the future. It takes a lot of time and money, but it’s worth it in the long run.

Increases Gas Mileage

In 2003 it became mandatory for companies to address the soot issue.

As you can imagine, this was a huge problem for humans and the environment. And thus, the DPF system was put in place.

To put it simply, the DPF catches toxic air contaminants through a fine screen that would otherwise end up going into the outside world.

But as good as that sounds, your gas mileage decreases because of this emission system.

Thus, drivers have opted to get rid of this poorly-made emission system. Once you’ve removed the DPF from your vehicle, your gas mileage will increase.

Increases Horsepower

If there’s one thing we can all agree on is that the fact that making more horsepower is always cool.

But your stock vehicle can only do so much. Cold air intakes, turbochargers are all well-known ways to increase your horsepower.

But those are not your only options. You can also make more power by replacing both the DPF and EGR.

While this is not a huge boost, it is noticeable enough to go through all this trouble.


It’s well known that the DPF requires a lot of maintenance, which is rather expensive. Getting rid of this device would free you from this never-ending and costly maintenance.

Cools Down Engine’s Temperature

No matter what vehicle you have, overheating is a common problem that car owners have to face every once in a while.

For that reason, DPF and EGR delete for 6.7 Powerstroke have become pretty famous among drivers.

That said, removing the EGR valve is a simple but efficient method to cool down the engine.

By removing this unit from your vehicle, the engine will have a much easier time breathing in, making it easier to reduce high temperatures.

Regen Cycles

Ever noticed a reduction in power as the vehicle is going down the road? Well, that’s the DPF for you.

As noted earlier, the DPF catches dirty particles that would otherwise end up being released into the environment.

In doing so, the filter eventually clogs up, and so the regeneration cycles kick in, helping the unit get rid of all these toxic particles.

However, this system can be somewhat annoying for drivers as it decreases power when driving. By getting rid of this system, you won’t have to put up with regen cycles anymore.

EGR Delete is Cheap

Up until now, we’ve talked about how expensive emission system delete kits can be — and we meant it. However, an EGR delete kit is on the budget side of things.

For instance, you can find a decent kit for $100. Furthermore, it’s not as hard to install as other modifications.

Decreases Engine Contamination

As we explained before, the EGR keeps pollutants out of the environment and protects your engine’s health.

However, over time, the EGR valve can accumulate many carbon deposits, clogging up the valve itself.

This is very problematic, and you must clean the valve before things get worse. While this process is not as complicated as you might imagine, it still takes time.

If you got rid of the EGR valve, carbon deposits wouldn’t build up inside, and you won’t worry about such trivial things anymore.

Deleting DPF & EGR Disadvantages on The 6.7 Powerstroke

Deleting both the DPF and EGR sounds pretty attractive for most drivers. However, it’s not all flying colors. Here’s what you need to know before deleting the emission system:

Car Warranty

Nobody wants to void their car warranty. Without it, the dealer won’t fix any defects your vehicle might have.

Unfortunately, installing a 6.7 Powerstroke EGR DPF delete kit will void your warranty. While this can be worth the trade-off, it’s a massive risk if your vehicle ever runs into a major issue.

It’s Expensive

Another major drawback is the price. Doing a full delete can be ridiculously expensive. Sure, it can save you money in the long run.

But if you don’t have thousands of dollars lying around, deleting the emission system might not sound too pleasant.

Moreover, finding delete kits in the United States is not easy.

Usually, if you find a mechanic who’s willing to delete your emission system, they’ll most likely include the kit along with the labor price, increasing the cost for this job.

You Won’t Pass Emission Test

Removing federally mandatory emission systems is illegal and can get you in trouble if you ever get caught.

Sure, you probably know countless drivers that got rid of the system and are doing just fine.

But if you don’t want to deal with that, you shouldn’t get rid of the emission system — especially if you’re in somewhere like New York, where you could quickly get in trouble.

It’s Not Easy for the Average Joe

With so many regulations against emission delete kits, it’s getting harder for drivers to get their hands on a delete kit.

Unless you’re in a country with not so many regulations against delete kits, you won’t get your hands on one of these kits so easily.

Increases Pollution

As you’ve seen, deleting the emission system has plenty of benefits as well as drawbacks. However, one of the biggest disadvantages is the increase in pollution.

This goes without saying, but if you get rid of the system designed to decrease pollution, your vehicle won’t have any way to stop those toxic contaminants from escaping the car.

Needs PCM Reprogramming

You might be able to install a delete kit, but you still need to reprogram the PCM for the DPF to work.

Unfortunately, if you don’t know how to flash the PCM, you’ll have to take the vehicle to the dealer.
