  • Improved Fuel Economy and Engine Longevity

6.6 duramax 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 with EGR delete kit, lower exhaust gas is produced, helps your vehicle to clean the intake air and reduce engine temperature

  • Save Money for Repairing

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.

    It's all there, I guess

    Everything arrived, but tube mounting plate was at wrong angle and holes in the wrong spot to receive the bolt. I would never buy this again. It works, but I ugly installation after modifying the tube to fit.

    Hi, if it doesn't fit, you can contact the customer service email to return it for a refund. Thanks!
