There are no high voltage spark plug wires for the SVX. The SVX uses a "coil on plug" ignition system. There are six coils, each attached directly to a spark plug. The wires going to the coils do not need to be replaced.
The best plug is debateable. The original plugs looked perfect when I removed them. No sign of wear or shortcircuit at all. I'm using the Bosch Platinum +4 at the moment. I think it ran better when I changed them, but its hard to say. Another good plug would be the Denso Iridium plug.

Same thing happened to me. I replaced my plugs a few months ago, the originals looked fine, but it seems to run better now. I used iridium plugs, I forget the brand. I got them from Dayle at motorsport.

I changed to the +4s about 25k miles ago, they were on sale and locally available at the time. Plus, I had no idea if the original owner had ever changed out the plugs, so I did it for "insurance".
No issues since then, my mileage has remained very stable at around 20.5mpg when just doing my normal day to day commuting.

I replaced my plugs with the OEM NGK platinums (PFR6B-11) at 133k miles. The originals were dirty, but all were gapped to spec and gapped identically. I couldn't say whether or not I saw a performance increase or anything because my car had been in storage all winter when I did the work.
I will say that going 30k miles without a 'tune-up' is hardly difficult for the EG33. The plugs are supposed to last at least 100k miles and mine were fine at 133k. If your engine is missing, I would find out whether or not your ECU is storing any fault codes.
