An EGR (Exhaust Gas Recirculation) delete on a 6.7 Cummins diesel engine involves the removal or disabling of the EGR system. The primary purpose of this modification is to improve engine performance and potentially reduce maintenance costs. Here's what an EGR delete does on a 6.7 Cummins:
Improved Engine Performance: The EGR system recirculates a portion of exhaust gases back into the engine's intake manifold 6.7 cummins egr delete bracket. While this is effective for reducing nitrogen oxides (NOx) emissions, it can have a negative impact on engine performance. By deleting the EGR system, some users claim to experience increased power, better throttle response, and potentially better fuel efficiency.
Reduced Maintenance Costs: EGR systems can be prone to carbon buildup and clogging, which can lead to reduced engine performance over time. Deleting the EGR system can reduce the need for EGR system maintenance, potentially saving on repair and maintenance costs like more youtube link.
It's important to consider the following caveats and cautions:
Legal and Regulatory Issues: Deleting the EGR system is often illegal in many regions, as it violates emissions regulations and air quality standards. Engaging in such modifications can result in fines or penalties if discovered during emissions inspections or audits. It's crucial to research the laws and regulations in your area before considering EGR delete modifications.
Warranty Implications: Modifying your vehicle with an EGR delete may void your vehicle's warranty, including engine and emissions-related warranties. As a result, you may be responsible for all repair costs should something go wrong with the engine or related systems.
Environmental Impact: EGR systems are designed to reduce harmful emissions, and deleting them can lead to increased emissions of NOx and particulate matter, which are harmful to both the environment and human health. Therefore, EGR delete modifications can have a negative impact on air quality.
Selective Use: EGR delete modifications are most commonly associated with older diesel engines that lack advanced emissions control technology. Newer engines may have more efficient emissions control systems that strike a better balance between emissions and engine performance. The appropriateness of an EGR delete can vary depending on the engine's design and emissions control system.
In conclusion, an EGR delete on a 6.7 Cummins can potentially improve engine performance and reduce maintenance costs. However, it's crucial to understand and consider the legal, warranty, and environmental consequences before proceeding with such modifications.
