When you buy on Amazon, make sure you buy directly from the manufacturer. You are right. A bosch ignition coil costs $34 at the official bosch store in amazon, while it costs $60 at advanced auto parts.

Pros: official store, lower price
Cons: higher price elsewhere

If you do replace a coil, go with OEM or quality aftermarket parts. Cheap coils cause new problems. The Hitachi coils on RockAuto are probably alright.

Pros: quality aftermarket parts
Cons: cheap coils cause problems

I got the coil conversion kit from import car parts and GD 2.0l coils. The new age coils needed to be trimmed a little from the edges to fit. I bought hitachi coils instead of oem diamond ones and saved a lot of money. They work perfectly.

Pros: work perfectly, saved money
Cons: needed to be trimmed

Probably the coils. The Bosch coils I’ve used in the past on my 330Ci (same coils) lasted maybe 20K. Delphi are much better.

Pros: Delphi are much better
Cons: lasted maybe 20K

Stick with the stock Delphi’s. I went with Bosch recently and half of them died within a day (N55). FCP swapped them out, no questions asked, but still a PITA to do the work multiple times.

Pros: FCP swapped them out
Cons: half died within a day

I chose the cheaper Bosch ignition coil. When I got home, I realized the spring inside was significantly shorter than my old coil's spring. I made no risk of putting this in and brought it back. I learned that Bosch parts used to be made only in Germany and were excellent, but now many are made in the US or China and are poor quality. The one I got was definitely not the German quality.

Cons: shorter spring, poor quality
