I ordered one of these kits for my 2015 BMW F30. I knew this kit DOES NOT have a fitting to attach the vacuum line, but my BMW has a vacuum line running from the intake box into the engine. I had to drill a small hole and insert hose fitting. The kit isn't an exact fit, so be prepared to bend the heat shield housing to get it to seat right. I had to cut 3/4" off the smaller pipe for it to sit low enough in the box. Air filter is HUGE! Some mechanical experience is required. Two thumbs up
