Any idea what the "silencer" portion refers to if not the foam bit? It does seem odd that no petrol BMWs are equipped with this AFAIK, and i would imagine that if it were only for filtration purposes, the paired primary/secondary filtration configuration would be more common among the brand. The n/a vehicles seem to have an intake silencer built into the air duct (such as the 328, shown here: http://parts.bmwofsouthatlanta.com/s...roduct=8398318), but the 335i has the suction silencer label and no visible resonator/silencer, so perhaps it is just referring to the box. Hmmm, perplexed...
Yeah.....what he said.
