Your guide to diesel delete kits

Pondering on the idea of personally installing a diesel delete kit? Previous plunging in, it’s important to investigate. Diesel delete kits don’t follow a universal solution approach. Aftermarket modifications that remove certain emission system components, such as diesel particulate filters (DPFs), exhaust gas recirculation (EGR) systems, and selective catalytic reduction (SCR) systems. Are DEF, DPF, or possibly an EGR delete on your radar? Have you considered the implications for your truck guarantee? Don’t worry, we’re here to help. We understand that these queries may be challenging to address, so, we break down the basics of diesel delete kits!


The realm of diesel lubrication is awash with acronyms. In your exploration of choices, you’re likely to encounter three distinct acronyms, each denoting a different kind of delete kit.

Diesel delete kits primarily serve to eliminate specific elements of a vehicle’s emission control system. These parts aim to lessen diesel engines’ environmental impact by minimizing the volume of harmful emissions produced. Yet, these same components may inadvertently hamper the vehicle’s performance and fuel economy, leading some drivers to opt for their removal through delete kits.

Many modern trucks come equipped with Diesel Exhaust Fluids (DEFs) as a standard feature. DEF systems work hand in hand with the factory-installed Selective Catalytic Reduction system to purify exhaust gases before they’re expelled into the environment. It’s vital to remember that DEF systems necessitate regular fluid refills to maintain optimal operation, a task that can be both monotonous and costly. Therefore, deciding to eradicate your DEF system could be a financially shrewd decision, potentially enhancing your exhaust’s tonal depth as well.


Designed to sift particles from your exhaust before they enter the atmosphere, these filters are built into your exhaust system. Over time, however, these filters can become clogged, negatively affecting the exhaust system’s performance. Ignoring their replacement could potentially result in a degradation of your truck’s performance. By removing these components, you could potentially save on future maintenance costs.

Turning our attention to the Exhaust Gas Recirculation (EGR) systems. To reduce nitrogen oxide emissions, the exhaust gas recirculation system recirculates a portion of the exhaust gas back into the engine cylinders. An EGR delete removes this system from the vehicle.. Nevertheless, this process could induce additional strain on your engine and undermine its efficiency. Implementing an EGR delete could prove advantageous in garnering more distance from your truck’s engine.


Regrettably, the Environmental Protection Agency (EPA) enforces rigorous rules surrounding diesel deletes. Often, DEFs, DPFs, and EGRs are legally mandated for newer trucks that come fitted with these systems. If your truck is subject to emission tests, the removal of these systems could lead to substantial penalties. However, emissions requirements vary by state, so be sure to check your local regulations to avoid potential penalties.


One potential issue with the installation of a diesel delete kit is the possible nullification of your truck’s factory warranty. In the event of truck malfunction, bringing it to a dealership for service might reveal that your warranty has been rendered void due to the installation of a diesel delete kit. However, if your truck is older, the expiration of your warranty might make this a non-issue.

It can feel like unraveling the mysteries of rocket science to navigate the complexities of diesel delete kits. Whether you decide on a DPF, EGR or DEFdelete, there’s an appropriate option for every truck owner. Remember to check local emissions regulations and whether modifying your exhaust system will void your manufacturer’s warranty before you take the plunge. Hopefully this brief guide has provided a solid foundation of everything you need to know about diesel delete kits
