Ignition Coil

I just got my 2001 325 ci back from the dealership getting serviced. They told me I will need a new ignition coil within the year. If i have to replace this part anyway i might as well upgrade.
Is there any way to increase performance with a specific ignition coil?
anyone have any suggestions of ones to buy ?
any idea what im looking for to buy one of these?

Thanks.

I recently had the Bavarian Autosport coils installed in my E39. Honestly, I can't really tell a huge difference over stock. I feel that the motor is more willing to rev, but I haven't noticed a huge change.

Coils normally don't fail unless they were defective in the first place. Quite a few e46 coils got replaced on warrantee. Around 2003 model year, I think. I have never heard of someone predicting that a coil would fail within a year. That sounds suspect.

I would not expect to see any increase in performance from different coils on a normally aspirated car running within the original RPM redline.
