m325i 705 Report post Posted March 3, 2016 Used between the MAF sensor housing to the throttle body. Allows for a dramatic increase in airflow over the stock intake tube. Smooth out the incoming air to the throttle body. Also can be used to upgrade the Stage 1 design to Stage 2. $100 shipped Quote Share this post Link to post Share on other sites
