To my untrained eyes the old plugs looked like that had some wear left but I felt that 100,000 is enough. |

But I know it won't run fine for sure with a bad coil and bad Plugs kills Coil. 6 spark plugs are about $60 One coil is around $30 So you can do the math, you would end up throwing more money away when you need to replace 6 spark plugs and few coils. Plus old and over used spark plugs loses some power. Bmw recommend changing it every 45k. They don't recommend for no reason. Do whatever you want change your sparks at 100k oil change 10k or don't change it at all. But will see whose car would be in a better shape I guess.
