When ordering ignition coil parts for German cars you rely on the info your auto parts supplier tells you. I ordered ignition coils for my Audi A8L and after inputting my vehicle information was told via the website the parts ordered fit my vehicle perfectly. However, upon receipt, the ignition coils were too short. (Picture attached shows original part vs. incorrect part received). I would advise UnoTuring to request VIN info for a more reliable part determination other than just Year, Make and engine! This cost me unnecessary time to hunt down and outsource with another supplier at an increased cost in order to complete my project on time.
