2004 Hyundai XG350 Question: spark plug replacement
Answer #1Bret Bodas from RepairPal Test Shop, September 29, 2009, 12:15Master
It's hard to believe the wires need replacing on a 2004 vehicle. How many miles do you have on your vehicle? Is this for regular maintenance or is there a problem with engine misfiring? What is their reasoning for replacing the wires?
