How long "should" these last?

Well, in a Car no less than 100,000 miles. Used in a marine engine V8 no less than 200 hours.

does this plug fit the oto guzzi breva 850 2008 model?

good night, which would serve me for a 92 eclipse 4g63 engine?

I can't say other plugs are not good enough, however after several months and many thousand miles how the NGK BPR6EIX Iridium IX Spark Plugs perform. Zero hesitation, burn clean, no misses and whether it is only the plugs or a combination of new wires and plugs, I am very pleased and will stick to these plugs for my turbo 2 L engine.... I also feel price evens out as they will last as long as 2 sets if others..
