What Are The Benefits of EGR Delete?
An EGR delete can bring about several benefits. These include:
Improved Fuel Economy and Engine Longevity
An EGR delete helps you restore your diesel engine’s power levels which, in turn, also restores your overall fuel efficiency. Since an EGR delete kit sends the exhaust gas away from your car’s engine, it starts to run cleaner, too. Not only does it make the process increasingly efficient, but it also reduces the chances of DPF (diesel particulate filter) failure. So, overall, with this aftermarket kit, you can see an increase of up to 20% in your fuel economy. Along with that, the EGR delete kit can also improve your engine’s longevity.
Reduced Engine Temperature
EGR valves naturally contain a high content of soot. When the EGR system’s valve or coolers get clogged with soot, the exhaust gases start to circulate more around the system, resulting in a blockage. As a result, the temperatures around the engine rise and you experience a reduction in the engine’s power. However, when you bypass this, lower exhaust gas is produced. In turn, during operation, your vehicle experiences a reduced engine coolant temperature.
Helps Save Money
In addition, an EGR delete can also help you save money on some costly repairs. The EGR, if damaged, can be quite costly to repair and replace. An EGR delete removes the possibility of such damage, thereby saving your money.
FAQ
Q1. Will this LLY EGR Delete Kit affect engine reliability?
No—in fact, it improves long-term engine reliability. The SPELAB LLY EGR Delete Kit eliminates hot exhaust gas recirculation, reducing carbon buildup in the intake system and lowering combustion temperatures. This helps extend the life of your turbocharger, intake manifold, and engine components.
Q2. Will I get a check engine light after installing the LLY Duramax EGR Delete Kit?
Without proper ECU tuning, you may trigger engine codes or limp mode. We recommend pairing any LLY Duramax EGR Delete Kit with a custom tune using EFI Live, HP Tuners, or similar software to disable EGR-related diagnostics and ensure smooth performance.
Q3. Does the SPELAB LLY EGR Delete kit include a high-flow intake pipe?
Yes. This kit comes with a high-flow intake tube designed to improve airflow and combustion efficiency. It provides a solid upgrade foundation for tuned or performance-modified LLY Duramax trucks.
Q4. Can I install the 2005 Duramax EGR Delete Kit from SPELAB myself?
Yes. The 2005 Duramax EGR Delete Kit is a bolt-on solution with complete hardware included. It's suitable for experienced DIYers with basic mechanical skills. We recommend watching an install video or referencing the manual before starting—most installs take 2–3 hours.
Q5. Is an LLY EGR Delete kit legal for on-road use?
No. Any form of LLY EGR delete is intended for off-road, race, or non-highway use only. It is not emissions-compliant for public roads in most states, including California. Please check your local laws before purchase and installation.
