EGR Delete Kits and Explanation

The Exhaust Gas Recirculation (EGR) system is critical in modern diesel engines. The EGR system recirculates a portion of the exhaust gases back into the engine’s intake system to reduce nitrogen oxide (NOx) emissions. However, over time, the EGR system can become clogged with soot and other debris, leading to poor engine performance and reduced fuel efficiency. This is where an EGR Delete Kit comes in.

What is an EGR Delete Kit?

EGR delete kits for diesel engines are an aftermarket upgrade that removes or bypasses the EGR system from the engine. The kit typically includes a block-off plate or plug to replace the EGR valve, a new intake manifold, and a reprogrammed engine control unit (ECU) to adjust the engine’s air/fuel ratio and ignition timing.

Why Install an EGR Delete Kit?

There are several reasons why diesel truck owners might consider installing an EGR Delete Kit. One of the primary reasons is to improve engine performance. The EGR system recirculates hot, sooty exhaust gases back into the engine’s intake system, reducing the amount of fresh air available for combustion. This can lead to reduced horsepower, poor fuel efficiency, and increased engine wear and tear. Removing the EGR system can improve engine performance and increase fuel efficiency, especially for diesel engines used in towing or heavy-duty applications.

Another reason to install an EGR Delete Kit is to prevent future engine problems. The EGR system is prone to clogging and failure, which can lead to costly repairs down the road. By removing the EGR system, diesel truck owners can eliminate this potential problem and save money on future repairs.

Are there any downsides to EGR Delete Kits?

While there are benefits to installing an EGR Delete Kit, there are also some downsides to consider. One of the primary concerns is the potential for increased emissions. Removing the EGR system can increase NOx emissions, which can be harmful to the environment. Additionally, some states and municipalities have laws and regulations that prohibit the removal or modification of emissions control systems, including the EGR system.

Another potential downside of an EGR Delete Kit is the impact on engine longevity. The EGR system reduces engine wear and tear by recirculating exhaust gases and reducing combustion temperatures. Removing the EGR system can increase combustion temperatures and potentially reduce engine lifespan.


An EGR Delete Kit can be a valuable upgrade for diesel truck owners looking to improve engines performance and prevent future engine problems. However, it’s essential to weigh the benefits against the potential downsides before investing. Diesel truck owners should also research their state and local laws regarding emissions control systems before installing an EGR Delete Kit. Ultimately, the decision to install an EGR Delete Kit should be based on the individual’s specific needs and circumstances.
