Hello, I just bought a '98 Jetta GLX VR6 and noticed that one of the cylinders is misfiring occasionally. I looked into it a little and noticed that it's definitely one of the plug wires. The spark plugs themselves seem fairly new and the spark is high enough that I am confident it's the plug wire. I'm planning to replace all the plug wires, but I was wondering what I should get. I can tell that the ones already on the car aren't VW factory ones. What are the most reliable plug wires that will be economical too? Should I get factory ones? I don't care about increasing power or anything like that, I just want to buy some plug wires that will last and are priced fairly low. Any insight I could get would be very well appreciated! Thanks!
