When I have been around diesel trucks long enough, I will begin to see one thing, the owners talk. It can be at a rest stop, a jobsite, a garage, and even a late-night online discussion, the truck drivers will tell what works, what fails, and what actually makes a difference under the hood. One upgrade that is continually reoccurring, year after year, is the egr delete kit.
I did not realize the existence of EGR deletes until I heard about it first-hand when a long-time driver explained that he needed his truck to run long distances. He was not attempting to increase horsepower or numbers. He simply wished that the engine would not choke on soot. I knew his experience, and at one point, I also got into the same problems. That is when I understood why the egr delete kits have become one of the most discussed changes in the diesel community.
Understanding What an EGR Delete Kit Really Does
The Exhaust Gas Recirculation system was made with the right intentions. The idea is to decrease the emissions of nitrogen oxide by diverting some of the exhaust into the intake. However, what may work well on paper does not necessarily work well in the field of diesel. With time, thick deposits of soot appear in the EGR valve, cooler and passages in the engine, decelerating the airflow and overworking the engine.
An egr delete kit stops this loop all the way through. The engine inhales fresh air as opposed to breathing burnt recycled exhaust. The difference was obvious since the first time I tried a truck with a full delete installed. Idle straightened, the acceleration was more instinctive, and an element of hesitation which would otherwise be evident in entering the highway was gone in a flash.
Why Diesel Drivers Prefer EGR Delete Kits
Just take a few minutes and talk to owners that rely on their trucks as a means of livelihood and you will hear the same frustrations. Constant check engine lights, clogged coolers, heat spikes, sluggish cold starts, these problems are likely to border on the EGR system. As soon as a person finally puts an egr delete kit on, the burden is relieved.
Most owners report:
- Better airflow and quicker throttle response
- Reduced soot buildup in the intake
- Lower engine temperatures
- More reliable performance on long hauls
In my situation, the initial truck which I maintained following a delete had been experiencing recurrent failures in the EGR cooler. This was a real money cost to the owner as the owner had already paid numerous cleanings and the downtime was taking money. He changed his maintenance schedule once he installed a delete kit, and within months he stopped experiencing the problems he had been having on a weekly basis.
Performance Gains Worth Talking About
Not all install egr eliminate kits to work on the performance and the performance is composed of the gains. Once the engine is no longer struggling with dense carbon formation and limited air supply, all functions are freer.
Drivers often mention:
- Faster turbo spooling
- More consistent power when towing
- Noticeable fuel savings during long-distance driving
My personal tests conformed to these reports. The voice of the engine even alters, it is more healthy, smooth and confident. Even minor enhancements such as this add up quickly to trucks that travel thousands of miles monthly.
A Cleaner System Means a Longer-Lasting Engine
The health of their engines is among the largest motivators behind the attraction of diesel owners to delete kits. The removal of the soot and recirculated exhaust of the intake path makes all parts of the pistons and sensors cleaner. Mechanics usually refer to it as letting the truck breathe as it was intended to.
I had checked an engine that had covered more than 200,000 miles after deleting it. Some of the newer trucks were using active EGR systems, but the intake manifold was cleaner. That is the type of difference that will keep drivers adherent to the upgrade.

Important Considerations Before Choosing an EGR Delete Kit
Nevertheless, the drawbacks given, it is crucial to note that EGR changes can potentially carry implications for emissions depending on the local regulations. Prior to installing egr delete kits, truck owners are advised to look at area regulations to prevent legal problems.
Technically, however, delete kits still remain one of the most reliable means to decrease engine load, prevent costly repairs and restore stable performance. It is, in fact, the reason why Trucktok is witnessing such a plethora of diesel owners considering these sorts of kits as a long-term maintenance plan.
Final Thoughts
Regardless of whether you are passing across the nation, transporting equipment day by day, or just desire your diesel to perform the way it was meant to, there is actual, quantifiable savings made with an egr delete kits upgrade. It is no wonder that the owners of diesel still recommend it to others including the longer engine life and smooth acceleration as well as less stress on maintenance. We have observed at Trucktok how much confidence and dependability this upgrade adds back to a truck at work.
