geoff malter Posted September 23, 2009 Share Posted September 23, 2009 How often should these be replaced? I have one independent garage quoting me 1/3 more for a 120k service than the dealer, on the basis that the spark plug wires should be automatically changed out at that service. The required maintenance is to replace spark plugs, but the book doesn't even mention to inspect the wires at that service. And does anyone know of any quality differences between OEM wires and NAPA (the independent is a NAPA shop and I suspect they replace everything with NAPA products)? Thanks in advance for replies.

djspawn00 Posted September 24, 2009 Share Posted September 24, 2009 Use only OEM plugs... I used an NGK wire set because it was the only thing available at the time. I'm not sure if it was necessary but I figured for another $50 why not... Quote Link to comment Share on other sites More sharing options...
