For owners of trucks with a 6.6-liter Duramax diesel engine, the EGR delete 6.6 Duramax is one of the best performance upgrades that reduces maintenance problems. The EGR system from the factory is made to bridge exhaust gas back into the intake to help emissions. Although it meets areas of emission standards; it can one day cause carbon-up attacks, stranded airflow, and diminished engine efficiency.
An EGR-delete kit for the 6.6 Duramax simply removes the factory EGR valve, cooler, and auxiliary components and provides a cleaner air path through which the engine breathes and operates more efficiently.
What 6.6 Duramax EGR Remove Kit Does
The EGR system on a 6.6 Duramax engine mixes fresh air into the intake to reduce combustion temperatures. Eventually, soot will begin to accumulate inside the intake manifold and cooler clogging the airflow and reducing performance.
The 6.6 Duramax EGR delete kit takes everything, including the block plates, rerouted coolant lines, and support bracket, creating a straight shot into the engine. Indeed, no hot exhaust gasses become mixed into the intake thus preventing carbon buildup while enhancing efficiency.
Benefits of an EGR Delete 6.6 Duramax
Improved Engine Airflow
The EGR system can be removed so that the engine brings in fresher, cooler air. That in turn supports smoother combustion and better responsiveness under load.
Lower Carbon and Soot Accumulation
Without having exhaust recirculated back into the intake manifold and into the cooler, there shouldn’t be any problems with maintenance from too much soot building up in one or the other. As a bonus, the cleaner the engine is kept, the less maintenance it requires over time.
Less Complicated Engine Setup
Delete Kit takes off all of that and replaces it all with a much more streamlined arrangement, thus reducing the number of potential failure points and simplifying maintenance.
Durable Construction
Block-off plates, brackets, and hoses in a high-quality delete kit are all made to withstand the environment internally in a heavy-duty diesel engine bay, including heat and vibration.
Installation and Tuning Considerations
A typical installation of a typical 6.6 Duramax EGR delete is to remove the factory EGR valve and cooler and put on the install hardware. Because the EGR system is monitored by the engine computer, most people will add a compatible ECU tune or programmer to the delete to either prevent any diagnostic trouble codes or throttle up the engine’s performance.
Proper installation ensures all seals are secure to prevent air or coolant leaks while maximizing airflow and efficiency.
Who Should Consider This Upgrade?
The truck owner who frequently tows, hauls heavy loads, or wants to deal with less maintenance from carbon accumulation should consider this upgrade. A properly installed and tuned 6.6 Duramax EGR delete goes a long way toward cleaner intake passages and reliable engine performance under demanding circumstances.
Final Thoughts
Getting an EGR delete 6.6 Duramax is one of the best ways to upgrade practically and towards performance in a Duramax diesel engine. Airflow is enhanced, carbon and soot accumulation reduced, and the intake system made simpler for the OSIAS engine. Thus, a proper EGR delete kit is a valid consideration for those who want better performance and easier maintenance.
