Because of more stringent pollution regulations for diesel vehicles, Ford introduced the 6.7 Powerstroke in 2011. After three generations since its debut, it has grown even more environmentally friendly. 6.7 Powerstroke emissions systems, on the other hand, have a high failure rate and are costly to fix.
As good as the diesel particulate filter is in reducing emissions, it has several drawbacks. Clogs are a common problem with the Dpf system. To make matters worse, the turbo suffers from a frequent issue with the 6.7 Powerstroke, which is excessive back pressure in the exhaust system. Finally, if the Dpf system breaks, a replacement may cost between $3k and $5k.
The removal of the system is a common thing that people do. This can cause 6.7 Powerstroke Dpf Delete problems. In this article, the Dpf system will be examined in detail, as well as the advantages and disadvantages of removing it.
What Is A 6.7 Powerstroke DPF?
Diesel particulate filter, or Dpf, is what it is called. Diesel particles are emitted into the atmosphere when diesel fuel is burned. Ingestion of diesel particulates may be damaging to both the environment and human health since they include a wide range of toxic compounds. Capturing and burning these diesel particles is done by the Dpf, which is a filter.
The 6.7 Powerstroke exhaust system’s Dpf is the engine’s third major source of emissions. The first is the diesel oxidation catalyst (DOC), which is effectively a catalytic converter and bolts directly to the downpipe. This is followed by the SCR system, which stands for selective catalytic reduction. To convert nitrous oxide into nitrogen gas and water vapor, the SCR system employs diesel exhaust fluid (DEF). Afterward, the exhaust gases enter the Dpf system, which burns them down as much as feasible.
The EGR system is another important emissions system to mention. Exhaust gas recirculation happens before entering the exhaust system and is called EGR for short. To further minimize emissions, the EGR system recirculates combustion exhaust gas back into the intake system.
What Is Removed When You Delete A DPF?
Because the Dpf is just one of four emissions systems, Dpf removals may be a bit of a challenge. However, a normal Dpf removal kit removes the DOC, SCR, and Dpf systems. Consumer pickup trucks use a single pipe for both SCR and Dpf systems. The Dpf is incorporated into the DOC in chassis cab work vehicles, whereas the SCR system is independent.
In other words, removing the 6.7 Powerstroke Dpf will get rid of
- Diesel exhaust fluid (DEF)
- Diesel oxidation catalyst (DOC)
- Selective Cat Reduction (SCR)
- Diesel particulate filter (DPF)
When the SCR system is removed, the DEF fluid is no longer required since it is solely used by the SCR system. Alternatively, you may just seal the DEF tank and leave it in place.
In essence, a Dpf deletion kit is nothing more than the length of the exhaust pipe. The downpipe and the muffler are connected through bolts, and all of the emissions components between them are removed.
Pros of 6.7 Powerstroke Dpf Delete
Reliability and performance are the primary reasons for removing the 6.7 Powerstroke Dpf. A brand new OEM replacement Dpf system costs roughly $4k and is prone to clogging and failure. The turbocharger, a typical failure point, is less reliable as a result. Secondly, it causes a lot of backpressures, which is terrible for the turbo and lowers the engine’s output.
- Gains of 30 to 100 hp (with a tune)
- Increase of 2 to 5 mpg
- Reduced backpressure in the exhaust system
- Turbos become more dependable and efficient
- Regen and DEF fluids are no longer required.
- A greater level of stability and reduced operating expenses.
- If you have an OEM computer, you can sell it for a lot of money.
A tuning is needed to remove the Dpf system. As a result, the most important factor affecting your ability to generate more power is the song you are using. With that said, even a slight tweak will result in significant advantages.
All of the other advantages are dependability and lowering maintenance expenses. Because you won’t be using DEF fluid at the gas station, you’ll save money. The loss of mpg is due to SCR’s ability to inject diesel fuel into the exhaust system, which reduces efficiency. Finally, if the Dpf system malfunctions or clogs, you won’t be stuck with a large repair bill.
Problems Or Disadvantages Of Dpf Delete
In terms of power, maintenance, and prices, removing the DPF system is excellent. However, the emissions, warranty, resale value, and a slew of other issues aren’t all that fantastic.
- Reduced marketability (have to sell private or reinstall OEM equipment)
- The installation must be performed by the user.
- As a result, the dealership may refuse to service your vehicle.
- It’s unlawful and won’t pass emissions regulations.
- Environmentally, it’s bad news.
- Because a tuner is required, the price is a little more.
The EPA is taking emissions manipulation extremely seriously. There is a good chance that a store will refuse to do this for you because of this. Additionally, you may run across a few mechanics that refuse to service your vehicle. Any warranty you may have will be voided if you don’t do this.
There are other factors to take into account, such as resale value and disposal costs. A DPF-capable tuner is required, and this may cost upwards of $500. You’ll lose money if you attempt to resell it without including the original equipment. To sell it privately, you’ll need to register it in a county or state that doesn’t allow emissions.
Is It Good To Delete A 6.7 Powerstroke?
The answer to this question is both yes and no. While there are many benefits to deleting the 6.7 Powerstroke‘s DPF system, there are also a few drawbacks that you should be aware of before making your decision. Ultimately, it is up to you to weigh the pros and cons and decide whether or not deleting the DPF system is the right choice for you.
Does DPF Delete Damage Engine?
No, a Dpf delete will not damage your engine. It can improve your engine’s performance and reliability by reducing back pressure and freeing up the turbocharger. However, you will need to tune your engine to compensate for the loss of the Dpf system, and this may void your warranty. Additionally, deleting your Dpf may be illegal in your area and can negatively impact resale value.
Should I Dpf Delete My 6.7 Powerstroke?
The advantages in power, MPG, and peace of mind are all fantastic. There are, of course, significant disadvantages. Unless you’re looking for extreme power increases or don’t want to spend $5k correcting a broken Dpf, we don’t propose eliminating your Dpf system.
Delete the 6.7 Powerstroke Dpf if you’re not in any of these cases. Inspections, maintenance become more difficult and there are substantial consequences, including having your vehicle crushed, for being detected with removed emissions systems.
The standard Dpf system should suffice if you decide to remove this component from your vehicle. Although selling it for $2,000 may seem enticing, the ability to change it back onto the truck is essential if you ever want to sell the vehicle or run into complications with inspections and maintenance.
It’s more difficult to reverse the EGR system’s removal than it is to install it.
Can You Delete A 6.7 Powerstroke Without A Tuner?
A computer is the only source of power for today’s machines. If the hardware is removed, a tuner is required to inform the computer on board that it is still there and fully functional.
Since 6.7 Powerstroke delete kits eliminate many emissions-related sensors from the Dpf system, it is necessary to tune the system. A variety of emissions-related functions are controlled by these sensors, including regeneration and so on. For this reason, a tune must be put to your vehicle so that these things may be tuned out.
Without a tune, your Powerstroke will display a slew of check engine lights and you’ll almost certainly have troubles with its performance and maneuverability. This adds $700 to $1,000 to the total cost of removing the 6.7 Powerstroke Dpf.
