Complete EGR delete kit, designed for older BMW M47, M47N, M51, and M57 engines that don’t have an electric throttle body and use a regular hose clamp for the intake. EGR removal results in lower inlet air temperatures, improved reliability and performance, and less carbon buildup in the intake system. You can choose to purchase this kit with or without coolant plugs, which are made from high-quality aluminum and have an integrated air bleeder screw. These plugs are necessary if your car has an EGR cooler and you plan to remove it as well.
