Genuine OEM Audi EGR Recuperation Cooler, part number 03G131512AP. This component is crucial for the exhaust gas recirculation (EGR) system, cooling hot exhaust gases before they are recirculated into the engine intake. By reducing the temperature of the recirculated gases, it helps to lower combustion temperatures and reduce harmful nitrogen oxide (NOx) emissions. Constructed from durable metal, it weighs approximately 2.233 kg and measures 0.345m in length. Using a genuine OEM EGR cooler ensures optimal cooling efficiency, proper flow characteristics, and resistance to exhaust gas corrosion, vital for maintaining emissions compliance and engine health.
