The 2.0T EA888.3 engine features a Mass Airflow Sensor (MAF) housing that’s bolted to the factory intake system, which traditionally blocks the install of our intake systems. With this billet aluminum adapter, it simply slides over the APR intake system and connects to the factory MAF quickly and easily. The simple no-tool locking o-ring design allows it to adapt to the APR intake without extra clamps which may detract from the overall look of the system. Simply press it on to the intake, bolt it to the MAF, and enjoy your new intake system!
