The LB7 series of Duramax engines, which commenced manufacturing in the year 2003, are noted for their great strength, 2003 duramax egr delete kit smooth operation, and reliability at higher pressures. The EGR systems do tend to fail, and sometimes they can carbon up over time, which will eventually restrict airflow and increase engine temperatures. Hence, fitting an EGR delete kit on your 2003 Duramax can solve these problems so that the motor runs cleaner and much more efficiently.
What Is an EGR Delete Kit
The design of an EGR delete kit is such that it removes the EGR valve and cooler from the engine by preventing the flow of exhaust gas back into the intake. The aim of EGR is to reduce emission, but it is sending in dirty exhaust air into the combustion chamber, which forms soot and carbon deposits on the intake valves and manifold over time; this gradual build-up restricts airflow and in turn, power generation. By deleting the EGR, the intake air for the engine is pure clean air, making the engine run cooler, efficiently, and with the least possibility of clogging or overheating.
Advantages of EGR Delete Kit for 2003 Duramax
There are many advantages of installing an EGR delete kit on the 2003 Duramax. The first and most visible benefit is the smoother running engine with better throttle response. Since the intake no longer sees hot exhaust gases, the engine runs cooler, thus reducing the detrimental effect on engine components. Clean airflow increases combustion efficiency, which reduces soot formation, which in turn increases the life of the turbo and intake manifold, among other things. These two are the reasons other Duramax owners have cited to improve fuel economy and reduce maintenance; hence, the EGR delete kit is one of the more widely accepted and practical modifications.
