What Is an EGR Delete?
An EGR (Exhaust Gas Recirculation) delete is a modification done on diesel engines using a specific kit to remove the vehicle’s EGR system.
This system is designed to reduce nitrogen oxide emissions, but it can sometimes lead to reduced engine efficiency and power.
When the EGR system is deleted, it can result in improved engine performance and fuel economy.
However, it’s worth noting that an EGR delete is illegal in all 50 states as all vehicles are required to meet federal emissions standards.
The goal of an EGR delete is to prevent the exhaust gas from reentering the engine, thereby reducing carbon buildup and improving airflow to the engine.
Despite these potential benefits, the modification can lead to penalties for emissions component alteration.
