thats why you should just buy a coil and plug kit from fcp euro and change them all again anyway and this way you are covered for free replacements for life so you can swap again for next to nothing. I have an n54 pwrd car for 9 years now and I have never had a misfire issue, only when i first tuned it at 35k miles on my odometer and dealer replaced all 6 plugs coils and injectors and since then all i have done is coils and plugs 2 times and not because of misfires but as a preventative measure.. I got 155k on the odometer now..
