So we went back to Digi-Tec to ask them if they had saved the original parts (BMW Original airbox etc) but they could not be found. So I asked the manager of Digi-Tec if he thought month of waiting was acceptable customer service, which he actually thought. Also, Digi-Tec seemed to have no problem of using KSA ///M3 on pictures on their site under M3 E36 tuning. Oh well, I guess we all learned us a lesson here with Digi-Tec.
