Have you guys ever changed your spark plug wires and o2 sensors even though theres nothing wrong with them? Mine have 229k miles on them and have never been changed. I've been on the fence about doing it or not since I'm not sure if i'll be replacing parts just for the hell of it. Cant really find any concrete information online so I'm looking for your experience. Anything else i should look into changing while I'm at it? I've done normal stuff like air filters and spark plugs but not really much else. its probably been a few years since i've had a transmission flush done (been reading its not always the best thing to do).
