---tab Description--- An EGR delete improves fuel economy (up to 20%), reduces DPF failure risk, and extends engine life by preventing soot buildup. It lowers engine temperatures, restores power, and avoids costly EGR repairs. The engine runs cleaner and more efficiently without recirculating exhaust gases. Key Features Condition: 100% Brand New, Aftermarket Product Direct replacement. No installation instruction. No Glue Formulated for high-temperature applications, or heavy-duty use (such as towing, etc.). Replaces almost any cut gasket by making reliable, formed-in-place gaskets that resist cracking, shrinking and migrating caused by thermal cycling. Coats pre-cut gaskets to increase reliability. Temperature range -65u00b0F to 650u00b0F (-54u00b0C to 343u00b0C) intermittent; resists auto and shop fluids. ---tab Fitment--- 2004 2005 GMC Sierra 2500 3500 HD 6.6 LLY Duramax Diesel 2004 2005 Chevrolet Silverado 2500 3500 HD 6.6 LLY Duramax Diesel Note: make sure that the size and shape of the product match your car.

An EGR delete can bring about several benefits. These include: Improved Fuel Economy and Engine LongevityAn 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 TemperatureEGR 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 MoneyIn 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.
