"A"'s are the first revision, and "B"'s are the 2nd revision.

The revised 'B' Coil "suppose" to last longer than the original 'A' Version.

I thought the 100's were the first version and 100A's were the second version? The coils I just got were 100A's, and the ones I took off the car didn't have an 'A'.

the coils should stil bear the same part number..a revision may be a beter insulating material.. mostly thogh a new supplier or revision may be to blame

Yep, that is why I said:
