Review on Hitachi IGC0012 Ignition Coil by Sam Hawj

These are original 1999 Maxima coils and installing them immediately eliminated the Service Center Coming Soon indicator (after clearing codes with a scan tool). The code was set by the Nissan computer when the aftermarket coils were installed. The different electrical resistance of the aftermarket coils will result in an incorrect voltage across the coils which will be detected by the ECU (computer), causing the code to set. (Many states fail verification with a code set.)
