What do Bosch spark plug codes mean?

Bosch plugs also use a structured code to indicate thread size, hex size, reach, heat range, and electrode type. For example:

FR7DC+
F = 14mm thread
R = Resistor
7 = Heat range
D = 19mm reach
C = Copper core
+ = Enhanced electrode design

Each part of the code helps identify the plug’s exact specification.
