please tell me this...

why does NGK list the spark plug wires for a 99-00 Si B16a2 to be the same as 96-00 DX/CX, 96-00 EX and 92-95 EX/Si, but different for a B18c1/5?

I was always under the impression that b16a2 wires would certainly be the same as b18c1/5 wires and certainly different than a sohc at the valve cover SP hole ATLEAST

ok...

why does MSD list one wire set for 92-95 B17/B18C1 and another for 96-01 B18C1/5...and the set they list for the c1/5 is listed for the 99-00 Si B16a2

did the wires change from a 1992 DA GSR or a 1994 DC GSR to a 2001 Type R..and would they all NOT be the same wire as a B16a2?

The reason i ask is i am a manufacturer's rep for a major ignition company and am cleaning up their application guide...seems they also have some errors in their app guide, but looking at the competition's lists, it does not seem like anyone has it together reallly....

please confirm what you can for me. thanks.
