Re: Replaceing Spark Plug Wires
As Roy said, BE VERY CAREFUL to match EXACTLY the ends on the wire(s)/part numbers on the wire or wires, should you choose to replace more than your #4. Depending on what year yours is, the plug ends are different. A couple years ago, I had a similar problem, and both OEM p/n sets they sold me measured (ohms) out the same! You might want to check out/do a search in the FAQs for others who have asked the same question. A good starting point would be the thread:
Spark plug wire difference
Also to consider, is that if one wire is getting frail, what is the condition of the others? It's costly to replace them all, but at least that way, you know the condition.
