The 6.7L Cummins engine is known for its power and durability, and can be driven over 300,000 miles or even up to 500,000 miles with proper maintenance.DPF and EGR systems are designed to reduce emissions, but they can cause frequent repairs, increased fuel consumption, and a loss of power. Deleting these systems results in increased engine power, reduced maintenance, improved fuel consumption and, in some cases, longer engine life, provided they are operated properly and routine maintenance is adhered to.

The EGR delete kit is a key modification to enhance the performance of the 6.7L Cummins engine, but it may need to be replaced after extended use due to high temperatures, vibration and carbon buildup.

This article will break down why it should be replaced, the recommended replacement intervals, and introduce new products developed by SPELAB.

Why Do I Need to Replace the EGR Valve for 6.7 Cummins After 1 Year of Use?

EGR delete kits work by removing the EGR assembly and directly stopping the circulation of exhaust gases, but they need to deal with the high temperature gases remaining in the exhaust line (even if the EGR function is disabled), which typically reach temperatures above 400°C and up to 600° in extreme cases.

Even high-quality aluminum alloys or stainless steel materials can suffer from thermal fatigue, deformation or cracks when exposed to high temperatures for long periods of time. Furthermore, connecting parts may loosen due to long-term thermal expansion and cooling contraction, reducing sealing.

In addition, even though the Cummins EGR Delete Kit stops the circulation of exhaust gases, a small amount of carbon particles and oil vapors may still be deposited on the lines and baffles during engine operation, resulting in increased resistance to airflow. Rather than cleaning it out frequently, it should be replaced periodically.

On the other hand, the oil engine itself has a high level of vibration, and prolonged operation will have an effect on the fixing brackets and connectors of the EGR delete kit 6.7 Cummins, which may lead to loosening or wear. In particular, the bolts and gaskets connecting the Cummins 6.7 EGR delete may be fatigue damaged due to mechanical stress, affecting the sealing and stability of the entire system.

Some automotive diy enthusiasts install 6.7 Cummins EGR delete kits without completely removing or sealing the coolant pathway, which may result in coolant leaks and affect the life of the egr delete let kit. Also oil vapors may seep into the air intake system, making cleaning and maintenance more difficult.

When you drive in harsh environments (such as extreme cold, high humidity, or dusty environments) on a regular basis, the 6.7 Cummins EGR delete kit's materials deteriorate and contaminants build up at an accelerated rate.

If you also drive for long periods of time under high loads (such as heavy towing or off-roading) the wear and tear on the components will be even more severe.

When to Replace EGR Valve 6.7 Cummins?

Replacement frequency depends on driving conditions and engine usage:

• High-Usage Scenarios: If your vehicle travels more than 30,000 kilometers per year, tows heavy loads, idles for long periods, or is driven in dusty or rugged environments, SPELAB recommends replacing the Cummins EGR delete kit every 6 to 12 months.

• Normal Driving Conditions: For vehicles with moderate use, replacement every 12 to 24 months is sufficient.

Why Replace the EGR Elimination Kit With the SPELAB Version 2.0 EGR Delete Kit for 6.7 Cummins?

The material of the egr delete kit has a very large impact on the frequency of replacement, EGR delete kit for 6.7 Cummins is ordinary stainless steel (201), cast iron, ordinary aluminum alloy, and at the same time to meet any of the above conditions, then the frequency of replacement to keep in 6-12 months.

If the replacement uses high strength CNC machined aluminum alloy and 304/316 stainless steel SPELAB pro 6.7 Cummins egr delete kit, then you can keep 12-24 months, a whole 1 times longer service life! But that's just the basic operation.
