Benifits 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. Installation Make sure that the size and shape of the product match your car.Due to actual measurement by hand, there may be a 1-2cm error. ---tab Fitment--- 2004 2005 GMC Sierra 2500 3500 HD 6.6 LLY Duramax Diesel 2004 2005 Chevrolet Silverado 2500 3500 HD 6.6 LLLY Duramax Diesel ---tab Shipping & Returns--- Fast Shipping Policy Your order will be dispatched within 1-2 business days, and the package will arrive within your order's estimated date.
