      Mas aire

      El filtro deja pasar mucho mas aire, pero la caja del filtro es muy restrictiva. si haces la actualización m330 merece la pena una admisión completa.

      Plug and play.

      Unbelievably easy to install, even for someone as ham-****** as me. Definitely adds a bit of drama and character to the induction noise on hard acceleration.
