Thank you for the explanation.... but that makes me think. Maybe there was some kind of a problem with the quality of those plugs? It must have been a limited time issue because I have never had that problem. On the contrary, the car starts better and runs smoother on those plugs. And it's not just my car... but others as well. It's possible that Bosch released a bunch of faulty plugs some time ago and now all that remains is the bad reputation. I, myself, like those plugs a lot. Tom Niemczewski vin 6149 (in Poland!)

Very bad since these plugs are supposed to outlast the "standard" type. That's the main reason to spend the extra money, not a "better" plug, just able to last longer.
