EGR Delete vs. EGR Blanking: What’s the Difference?

Welcome to the AK Performance blog, where we delve into the world of vehicle modifications. 

In this article, we will explore the key distinctions between EGR Delete and EGR Blanking. As experts in the field, AK Performance is here to provide you with valuable insights to help you make informed decisions regarding your vehicle’s EGR system.

What is EGR Delete?

The EGR Delete process involves the complete removal of the EGR system components from your vehicle. The EGR (Exhaust Gas Recirculation) system is responsible for reducing emissions by recirculating a portion of exhaust gases back into the intake manifold. However, there are some compelling benefits associated with EGR Delete, such as:

  1. Improved Engine Performance and Power: By eliminating the EGR system, you can experience enhanced engine performance. The removal of exhaust gas recirculation allows for a cleaner intake of fresh air, leading to improved combustion and increased power output.
  1. Enhanced Fuel Efficiency: EGR Delete can also contribute to improved fuel efficiency. With a cleaner intake and more efficient combustion, your vehicle can achieve better mileage, helping you save on fuel costs in the long run.
  1. Reduced Carbon Deposits and Maintenance Costs: Eliminating the EGR system can minimize carbon deposits in the intake manifold and valves. This, in turn, reduces the risk of carbon build-up, which can lead to expensive maintenance and repair issues down the line.

Understanding EGR Blanking

EGR Blanking is a partial modification of the EGR system, where certain components are blocked or modified to restrict the flow of exhaust gases. One common method of EGR Blanking involves the use of EGR blanking plates. Here’s what you need to know:

EGR Blanking Plates

EGR blanking plates are physical barriers that are installed between the exhaust gas outlet and the EGR valve, effectively blocking the flow of exhaust gases. These plates are designed to fit specific vehicle models and can be easily installed or removed.

Advantages and Limitations of EGR Blanking

EGR Blanking, including the use of blanking plates, offers several advantages such as:
a. Improved Engine Performance and Response: EGR Blanking can lead to enhanced throttle response and acceleration by reducing the recirculation of exhaust gases, similar to EGR Delete.

b. Potential Legal and Environmental Concerns: It is important to note that EGR Blanking may not comply with emissions regulations in some areas. Additionally, blocking the EGR system completely can increase nitrogen oxide (NOx) emissions, which can have negative environmental impacts.

EGR Delete vs. EGR Blanking: What’s the Difference?

Now that we have explored EGR Delete and EGR Blanking, let’s compare the two methods:

EGR Delete

EGR Delete involves a comprehensive removal of the EGR system components, offering the following benefits:
a. Optimal Performance Gains: With EGR Delete, you can achieve the maximum performance gains due to the complete elimination of the EGR system.

b. Potential Legal Implications: It is crucial to consider the legality of EGR Delete in your area, as some regions have strict emissions regulations that prohibit such modifications.

EGR Blanking 

EGR Blanking, including the use of blanking plates, offers the following characteristics:
a. Partial Modification of the EGR System: EGR Blanking allows for partial modification, restricting the flow of exhaust gases while keeping some components intact.

b. Accessibility and Reversibility: EGR Blanking, including the use of blanking plates, is often more accessible and reversible compared to EGR Delete, allowing you to switch back to the original configuration if needed.

Factors to Consider when Choosing EGR Modification

When deciding between EGR Delete and EGR Blanking, it is essential to take the following factors into account:

  1. Vehicle Manufacturer’s Warranty Implications: Modifying your EGR system may void your vehicle manufacturer’s warranty. Ensure you understand the warranty terms and potential consequences before proceeding with any modifications.
  1. Legal Regulations and Emissions Standards: Familiarize yourself with the local regulations and emissions standards in your area to ensure compliance with the law.
  1. Desired Performance Improvements and Fuel Efficiency Gains: Consider your priorities when it comes to performance and fuel efficiency enhancements. Evaluate whether EGR Delete or EGR Blanking aligns better with your goals.
  1. Long-Term Maintenance and Costs: Factor in the long-term maintenance requirements and costs associated with EGR modifications. Consult with professionals, like AK Performance, to understand the implications and potential maintenance needs.


In conclusion, understanding the differences between EGR Delete and EGR Blanking is crucial when considering modifications to your vehicle’s EGR system. Each method offers its own set of benefits and considerations.

Remember, making an informed decision ensures you get the most out of your vehicle’s performance while staying compliant with regulations and preserving its longevity.
