The Bosch are known to break down quicker in our waste spark engines. It'* a simple fact that our plugs fire twice, once on the compression stroke and again on the exhaust stroke. This seems to kill the Bosch'rs quick.
You can run them, expect to be replacing them in 2-5 months though. At that time, I'd go with an Autolite or Delco replacement. NGK stopped getting my vote when half their plugs come through with screw on tops. This means it comes loose during heat cycles and causes KR until you track them down and retighten.
I'd rather drive than fight plugs constantly.
