There is the distinct possibility that the OEM plugs that were first placed on the VX from the factory might have been of a lower Ohmage per foot. Honda did some weird things to the car in order to squeeze every last drop of FE out of it. (insert picture of a VX oozing FE juice here, lol)
Teh problem I ran into personally with a Checker store in my area (Champlin, MN) was that the plug wires they had listed for the VX model with the same ones for the non-VTEC D15B7 (DX) model engine. The problem is that the top part of the plug boot that seats into the valve cover is too big and does not seal. This also keeps the lower part of the boot from making a good seal and connection to the spark plug itself.
In the eParts Catalog from Honda, it shows that all years of the VX and Si take the same plug wires. So that nicks my idea of special plug wires for the VX. It really comes down to less resistance per foot = better electron transfer. So go with what info you find for a wire that is lower resistance, and good reliability. Just be forewarned that going down to a true race style plug (almost 0 resistance per foot) may cause electromagnetic radio interference.
