Performing an EGR delete isn't as difficult as many people think. While it may increase your car's performance on the open road, the removal of the EGR system can also lead to legal issues. The removal of this system can make your car run hotter and produce more pollution. Also, it can make your vehicle unroad-legal and could lead to hefty fines. Whether you're planning to do this mod on your car or not depends on your personal preferences and budget.

An EGR delete kit disables the EGR valve and EGR cooler. This prevents the recirculation of exhaust gases. This modification can improve fuel efficiency by up to 20%. However, you should know that this method will mess up the engine's design and may cause other unwanted side effects. So, it's not a good idea to install an EGR delete kit unless you have a very good reason.

Getting an EGR delete kit is a relatively inexpensive DIY project. However, it does require professional installation. If you are a novice, you can try the procedure yourself to avoid the costs of hiring a technician. If you want to avoid the extra expense of hiring a mechanic, you can always buy an EGR delete kit from a supplier. However, this will cost you around $200, or even more. Also, you might have to tune your car's ECU after you install it.

While removing the EGR may not cost you a lot of money, it can cause significant problems in other parts of the engine. You can't expect a noticeable increase in air density after removing the EGR. This 1% increase isn't enough to affect the performance of your car. Besides, it also keeps your engine's input manifold clean. This will help your car run more efficiently. You should consult a professional EGR delete installer to know if you will need to remap your engine's ECU after deleting the EGR.

Another great benefit of an EGR delete kit is its fuel economy. The removal of the EGR helps restore fuel efficiency and power levels in diesel engines. As the exhaust gas is directed outside the engine, it is more efficient and reduces the risk of the diesel particulate filter failing. It can improve your car's gas mileage by 20% and even prolong the life of your engine. Many people opt for this solution to improve their car's performance. The cost of an EGR delete kit depends on your car.
