I have some super cheap "lifetime warranty" spark plug wires from advance for my truck. It's got 230,000ish miles on it, so I just do whatever it needs to stay running. That said, I replace the wires every few months when they start to cause a misfire....
My dad bought them when it was his truck initially, and I've easily replaced them 5 or 6 times, no charge each time . Quality, no. Value, yes!
Edit: Advance also consistently gives me the wrong parts when I go in there, namely brake pads for a different rear end, or a front o2 sensor instead of the rear, etc. etc.
