Re: Are there "arcproof" spark plug wires ??? (BarneeVRTEC)
nothing that i know of is 'arc proof.'
but the differences between the wires other than cost and colour are internal... 8mm or 9mm... i even think there are some 10mm wires out there. some claim that the only difference is the amount of coating around the wires. i've yet to see anyone chop up the sets to determine if there's any truth to that.
Re: Are there "arcproof" spark plug wires ??? (AxeYrCat)
Definitely no such thing as "arcproof". If you put a high enough voltage on that wire, it can arc. Any good set of wires will not arc under normal circumstances. In that respect, you should be fine buying virtually any brand of wires. If you're arcing now, then, the insulation is failing somehow (cracked, dry rotted, etc.) or the wire might be pulling off the connector to the spark plug, exposing wire.
As far as delivering a quality spark, look into lower resistance wires. The thicker the wire, the lower the internal resistance -> less voltage drop across the wire -> higher voltage at the plugs.
A thicker wire is not necessarily better! All else equal, then yes, thicker is better. But other factors such as wire/connector quality come into play too. If you're looking for a recommendation, here it is - stick to stock. Most everyone I've talked to agree that the stock wires are better than most aftermarket sets available. Quality BERU connectors, nice construction. And no, they won't arc.
