Why do spark plug wires have different part numbers if they are all the same?

For example:

ITR = 32722-P30-000
B16 (1999 Si) = 32722-P2T-000
B16 (1994 Del Sol) = 32722-P30-000

 

Length, diameter, rated specs, matrial, and manufacturer are all subject to be different.

 

I just find it on that the ITR and Del Sol run the same wires, but the 99 Si does not.

 

Well, I know that the H23 wires are too short for the H22, even though they are in the same generation of preludes.

I guess it's just "the man" stickin git to us, lol. IDK.
