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. Replacing the factory intake and airbox with the COBB SF Intake System will greatly reduce pre-turbo restrictions. When a restriction is removed, it allows the engine to be more efficient while also enabling it to make more overall power! The higher flowing intake also makes turbo and bypass valve noises more audible.
