You know about the Magnecore website on 4G63 wires? It's long, and goes on and on about moisture, oil, and other crap messing with your plugs and wires. The previous owner of my GS-T (not the brightest star in the night sky) had his stock wires replaced 3 times, with stock wires mind you, and they kept "arcing" or something like that. (whatever he told me) So anyways, I got the Mag 8.5mms, and NGK 7s (which I need to change) and I really haven't had any ignition/spark/wire problems at all. I guess performance wires are a lot better. Haven't heard the best reviews about Accel wires, but I hope they work out for you.
