Good morning, I have removed my air filter box from my 2.2i Z3 (M54B22) and to my surprise there is a resonator box bolted to it and a branch connection from the rubber boot. I have identified the rubber boot and resonator box as E39/E38 parts via Realoem. The resonator box is bolted to the filter box by, what appear to be, OEM bolts. My car was manufactured in December 2000, the filter box dated November 2000 and the resonator box August 2000.
Is this the OEM set up, or has the resonator box been added later, please? I have also found an eBay listing for a 3.0i filter box that has a resonator box attached - https://www.ebay.co.uk/itm/116310669071
