As the engines evolved and upgrades became a priority, one such upgrade was the introduction of the EGR system. But that did not come without compromise on the performance and efficiency of the engine. For that purpose, EGR delete kits were introduced, which stood out among many other choices available for removing such a system since they guarantee a higher power output and a longer engine life for your cherished vehicle. Let’s delve into the heart of this matter. 

Understanding the EGR System


EGR stands for Exhaust Gas Recirculation. It is a device that recycles some of the exhaust gases from the engine back to the engine cylinders in an effort to reduce the harmful emissions from your vehicle. It does so by lowering the temperature of the combustion chamber. Basically, when fuel and air are burnt in an internal combustion engine to produce power, a lot of heat is produced as a by-product, leading to the formation of Nitrogen Oxides. By cooling down the chamber, the combustion process leads to reduced formation of Nitrogen oxides, thereby preventing their harmful emission.

Now, you might be wondering why anybody would want to remove the EGR system if it's so important for emission control. That’s because it has its disadvantages. The EGR system cools the exhaust air before being redirected. The cooler the air inside the combustion chamber, the harder it becomes to combust. Furthermore, through the process of re-introducing exhaust gases into the combustion chamber, the EGR system may cause carbon deposits to accumulate, thereby diminishing its durability, power, and efficiency. And that is when the role of the EGR Delete Kit kicks in. An L5P delete kit functions by removing the EGR valve and stopping exhaust from returning to the engine.

What Does the Kit Include?

Now, let us focus on the components of an EGR delete kit.

  • Block-off plates: Closes off the opening of the old EGR system, stopping exhaust gases from entering the intake.
  • Gaskets: Ensures a tight seal, making sure no exhaust gases seep out.
  • Bolts: Fastens block-off plates to the engine, made especially to withstand high pressures and temperatures.
  • Coolant reroute hoses: Redirects the engine coolant, ensuring ideal operating temperature.

Benefits of Using the L5P EGR Delete Kit

Let’s take a moment to appreciate the benefits of using the L5P EGR Delete Kit.

  • Enhanced Vehicle Performance: Through the EGR system, exhaust gases are circulated back into the combustion chamber, which indicates that your engine may not be running as efficiently as it should be. This is because exhaust fumes disperse some fresh air-fuel mixture that might otherwise aid in burning. Using the EGR delete kit, your vehicle's engine gets access to more fresh air. The outcome? A more effective, cleaner combustion that yields more horsepower.
  • Extended Engine Lifespan: By nature, the EGR system feeds exhaust gases back into the engine. Over time, this process may cause carbon deposits and soot formation inside the engine. This accumulation of material may exacerbate wear and tear in the engine, thereby shortening its lifespan. By installing an EGR deletion kit, you can prevent these deposits and keep the internal engine environment clean. This may further result in fewer maintenance requirements and an increased engine lifespan.
  • Improved Fuel Efficiency: When your engine starts to run under better combustion conditions, it will be able to use fuel more efficiently. This efficiency will result in higher miles per gallon, which would save you money at the petrol station. Furthermore, you’ll also notice smoother acceleration with efficient engine and fuel usage.



A high-quality L5P delete kit comes with all components, and everything is included in the kit for a complete installation. One such product is the Chevy GMC Duramax Diesel L5P EGR Delete Kit. The available models range from years 2017-2023. This aluminum delete kit is available in black color.

Using basic hand tools, installation of the kit takes approximately 2 hours. Moreover, a DPF delete-capable tuner is necessary when installing an EGR delete in order to stop any check engine light or diagnostic fault codes from turning on. In case the engine light turns on, there are three ways to fix it:

  1. Take out the light sensor
  2. Take it to the repair shop so that a professional can remove it
  3. Buy a tuner to reprogram
