The Volkswagen SF Intake System for the MK6 GTI is constructed 3″ aluminum tubing, a custom aluminum airbox, and an intake filter. Mandrel bent and powder-coated black, the 3″” intake tube and custom airbox look great in the engine bay and increase potential airflow. The reusable filter can be cleaned and re-used for the life of your vehicle! This utilizes the stock MAF housing allowing it to work on the factory calibration and does not require tuning.
