Hey everybody!
My 2007 cobalt is getting some 100k maintenance and I plan on doing the tune up myself but I was wondering if I should change the spark plug wires in addition to the spark plugs. Obviously if there is any damage to the wires I will change them but is there a reason to change the wires if they look fine?

No wires, it has individual coil packs. I wouldn't change them unless there is some kind of problem with them
