So I swapped the OEM bmw ones last year (made by Delphi) nothing wrong with them just did as a preventative measure with new spark plugs as well before I added a jb4 tune at the time. About 7k miles later I get a misfire. I have MHD tablet so I hooked up what the CEL was "cylinder 6 misfire". Disappointed the coil pack didn't last very long. The car could barely accelerate from a stop and the car shook unpleasantly. I took a couple pics and ordered a whole new set of coils and sparks. Same model DELPHI coils. The tabs up top seem lesser quality but the rubber boots where it seems to matter more have a bit more quality than the first set I had in 2017.
The pic of the three coils are in this order: left is OEM bmw original coil. Middle misfire coil (rubber boot seems warped and aluminum part discolored, right third is new Delphi.
