Default S55 coils in N54? - 12-22-2014, 05:34 PM

Anyone doing this? Need new coils and this seems like a good idea since our Bosch ones are always failing.

I run them. But I think all N54 coils orders the metal design though now.

I was wondering about this. We were changing out Shea's plugs before NFZ AZ and I saw his coils and noticed they were different than mine. I looked on Turner's site and it didn't say the N54 coils were compatible with the N55 and vice versa. If you're running them then obviously it's okay to do. Maybe my next set will be S55/N55 coils. Any performance advantage or are they just the new and improved coils?

As a dealer tech who changes these bloody things out sometimes twice a day,

BMW uses 3 manufacturers for their coils

Bosch
Bremi
Delphi

Most of the n51/n52s has Bosch's then by the time they started going bad we replaced them with Bremi, which consequently also sucked, and so now were sticking in the new Delphi's which are the same as the N55, used this S55. THey are the superceed number for us, so now when n51/n52/n54's have been coming in for coils We have to replace all of them with the Delphi's if there's misfires on more than 2 cyls. You can't mix and match, though sometimes i've seen guys accidentally use the new ones mixed with old and don't see any problems.

long story short

they all do the same thing and will scope similarly on a same engine comparison
use them on any n52/n51/n54/n55
Must use all or none for best results
seems to be holding up the best and support the biggest beating , no rubber insulation to crack and a full metal body.

Are the delphi's for the s55 the same as the N55? Looks like different part #'s and different prices although they look the same
