Detailed how to guide on removing the sound tube on a Mazda MX-5 Miata ND2. I highly recommend this as the cabin is noticeably more quiet now that the rattily engine noise is gone. I never heard any real intake sound from it...I used a sound tube delete kit from Moss Miata: 910-894. Mazda parts bought separately are: PEFA-13-220 Hose and P51B-13-252 Grommet.
