a failing coil will show rich, poor burn.
those plugs dont look all that bad, but its hard to say whats really going on - and once you have stepped out of the stone age and dont have carburetors anymore a wideband O2 tells you so much more.
Turbo motors are hard on ignition components though, on the Audi I was replacing plugs every 10k and I swapped the coils twice during the time i owned it (3 years).
