When I bought my 330i, I did some maintenance on it and replaced all coils and plugs with around 58k on the odometer. I didn't notice any difference at all when I did the coils and plugs, so I'm pretty sure there isn't anything wrong with the ones I took out. I am selling them because I traded in the 330i saturday and no longer need them for spares. I'm selling 6 coils and 6 plugs for 50.00 shipped OBO. I can put up pics later when I get home if you would like to see everything. Hit me up!
