DPF stands for Diesel Particulate Filter. This name applauds us everything about what it is and what it is capable of. Diesel particulate filter is, in fact, a filter that is installed in the exhaust system of vehicles and is meant to filters soot and some other particulates from engine exhaust.

Not only this, but the soot is then stored in a specified and channelized compartment that is specifically added for this purpose, within the exhaust system until it is filled to its extreme. This way, it allows the vehicle to start with a process called regeneration cycle while using fuel to burn off the accumulated soot.


The DPF delete is mounted to meet all the requirements for the standards relating to emissions and exhaust of gases from the exhaust systems of the Diesel cars, made around 2007 for Diesel engine manufacturers.

DPF is included in the exhaust systems as a standard component in modern-day’s heavy-duty trucks or diesel cars. This is categorized as one of the most problematic components in a vehicle that not only harms its performance but also lessen up its fuel economy and increases the graph of maintenance.

That is why most of the manufacturers have now opted to remove this particulate filter from the vehicle as a common practice simply known as DPF Delete.

Have you ever had this question in your mind? “DPF Delete or DEF Delete”? A big question that vehicle owners are asking and expecting to get proper answer. Let’s take the tour to see what the answer is by following our review below.

Some common terms of vehicle that you may need to know: DPF or DEF, DOC, SCR, and EGR. These terms are very important. If you own vehicles, you should know these well. Understanding these terms can help you maintain your vehicles well.

What does the DPF Delete do?

DPF Delete is the way to get things better and channelize the fuel economy according to the standards. DPF was designed to capture soot and some other particulates from the exhaust gases before they were released in an open environment. But it had started posing presents logistical issues about cleaning exhaust gases as well as clogging things up to escalate the problem even further.

Over time, it is meant to clog the soot and other components, while paving the way of crucial maintenance relating to the engine and its operations as well. This way, unexpected maintenance is escalated cutting down the profits and increasing costs to runs and maintain. DPF limits the performance of the engine with a low fuel economy leading to performance and production issues. With these issues and problems, most of the drivers and fleet managers decided to have this DPF deleted.

Going on with DPF delete, it removes a vehicle’s problematic Diesel Particulate Filter and keeps the computer system on track to function without this DPF filter. For this purpose, DPF delete kits are available from many manufacturers. DPF delete kits are comprised of two main components, including the exhaust and the tuner. Out of these two components, the exhaust works on replacing the DPF, while the tuner is installed to disable the vehicle’s regeneration mode.

Does DPF Delete increase horsepower?

With a DPF delete kit being installed, your vehicle will have increased horsepower and better fuel economy. Not only this, but it escalates your vehicle’s life span.

DPF Delete 101

There are perks to owning a diesel-powered truck. There is very noticeable a difference between gasoline and diesel in terms of cost. In truth, diesel trucks costs more up front. Expect cost to be even higher if we are talking about heavy-duty truck models. But, those are just upfront costs. You will be able to get your investment back after a few years, since diesel-powered trucks are known to last longer than gasoline-powered ones. You will even end up saving money on diesel fuel. But the thing is, in order to get the most out of your diesel-powered truck, you need to do a few modifications. One of these modifications is the DPF Delete. This article will explain everything you need to know about DPF Delete.

What is DPF?

The combustion process in a diesel engine will result in two by-products. These by-products are gasses and solid particulates. These particulates are very much like soot. You really can’t do anything about the gasses, but for the solid particulates, it is filtered by the honeycomb structure of the diesel particulate filter (DPF in short) to prevent unnecessary emissions.

Ideally, this soot is burned through either active or passive ‘regeneration’. This is a process that should keep the filter clean and your engine running at full efficiency. The problem is,, DPFs have their own set of issues and are the center of a rampant controversy (we’ll talk about this in a bit).

DPF Disadvantages

In theory, DPFs are great, but the reality is quite different. The truth is, DPFs can cause lots of issues once you take an engine out of the lab and run it in the real world. First, DPFs have a limited lifespan. Its lifespan generally ranges from 50,000 to 150,000 miles, depending on how old the vehicle is. Then, it requires either professional cleaning or replacement from time to time. The cleaning and replacement isn’t also an easy task and will force you to add it to your budget every couple of years.

Other common issues associated with DPFs are those with the regeneration process. There is extended passive regeneration occurring when on long drives. This is initiated automatically when there is an increase in temperature. Since most owners of diesel-powered trucks operate in urban environments, so naturally, they don’t get enough open-road time. That’s why manufacturers have also included active regeneration cycles in most diesel engines.

This active regeneration cycle injects raw diesel into the exhaust system, thereby raising the temperature and initiating regeneration. But if either the active or passive regeneration is interrupted, the incineration will not be completed. The particles that were not properly burned will then clog the DPF.

The best-case-scenario is it will result in backpressure in the exhaust system, which will then lead to reduced engine efficiency, lower mileage and increased fuel consumption. The worst-case-scenario is it can result in your truck going into ‘limp mode’, which what you don’t really want because it will force you to bring the truck into a repair shop for a thorough cleaning or even replacement of the DPF. And as you know, that will be worth thousands of dollars in unwanted expenses.

What Are DPF Delete Kits?

Fortunately, there’s a simple solution to the issues presented above. If you want to get the best performance from a diesel engine, deleting or removing the DPF system of your engine is now a viable option. This has become popular in response to a growing demand from owners who want the full performance and fuel economy that their diesel-powered vehicles are designed to provide. All you need is to get a DPF Delete. But what exactly is a DPF Delete Kit? Let’s elaborate on that below.

DPF Delete kits are bolt on kits that can be easily fitted to your truck and replace the DPF. Upon installation, it will result in better airflow, better performance, and better fuel consumption for your engine. Plus, removing the DPF will also let you use certain Biofuels to power your truck. This is not possible if your engine is fitted with a DPF.

How Do You Remove The DPF System?

The removal of the DPF system is actually pretty simple and can actually be done by any mechanic worth his or her salt. Once the original DPF is removed, the mechanic has to install a replacement pipe to fill the gap in the exhaust system. The system will also need a diesel tuner to ensure that the sensors controlling your truck’s DPF regeneration cycle will not be affected by the delete.

You don’t have to worry though because when you purchase a DPF delete kit, these parts will be supplied. After the mechanic has removed the DPF, replaced it with the kit and reset the sensors, you will now notice an immediate and significant improvement in horsepower as well as torque. You will also see a reduction in fuel consumption. This is the mains reason why DPF delete kits are becoming more popular with truck owners who want maximum performance and improved fuel efficiency from their trucks.

Legal Implications of DPF Delete Kits

The main purpose of a DPF is to reduce diesel particulates emitted by your truck. Once you delete it, the obvious result will be an increase in emission. So this brings us to the question of legality. Deleting your DPF is allowable under certain conditions. Commonly, this is permissible for closed-track racing and other professional applications. You do have to be aware that a DPF delete kit cannot legally be installed on any vehicle registered or certified for highway use. This is due to the antiquated draconian legislation dating back almost 50 years. The Clean Air Act of 1970 prohibits owners the right to modify their vehicles as they see fit, even though there is an obvious and dramatic improvement in engine performance. There are also various state and local laws that can also be applied to removing the DPF system of your truck. So we recommend you find out how it could affect you before you pull the trigger. You might regret it later on.

So there you go. These are all the information you need to know about DPF Delete. Hopefully this article has clarified everythintg you wanted to know about DPF delete. Remember, it pays to be well informed.View more with
