SPELAB 2007.5-2010 6.6L Duramax LMM EGR Valve Cooler Delete Kit

The 2007.5-2010 6.6L Duramax LMM EGR Delete Kit includes a high-flow air charge pipe that replaces the restrictive factory plastic piping, dramatically improving airflow for enhanced turbo spool, throttle response, and overall engine efficiency. This upgrade maximizes combustion efficiency, lowers EGTs (exhaust gas temps), and supports future power modifications—making it ideal for towing, performance tuning, or daily driving.

Key Features

• Eliminates the weak, heat-soaked plastic OEM pipe (prone to cracking/leaks)
• Material: Stainless steel & billet aluminum
• Smoother, unrestricted airflow = better turbo efficiency & horsepower
• Reduces turbo lag for sharper acceleration
• Handles higher boost pressure (essential for tuned/modified engines)
• Corrosion-resistant & leak-proof

• 2007.5-2010 GMC Sierra 2500 3500 HD 6.6 LMM Duramax Diesel
• 2007.5-2010 Chevrolet Silverado 2500 3500 HD 6.6 LMM Duramax Diesel

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.

Function
Coolant temperature run cooler because they are not running through EGR Cooler. Eliminates soot build-up and clogged EGR Valves. Hot exhaust gasses are not being re-routed back into the motor.
