My 9-5 uses NGK BCPR7ES (copper) plugs in its 2.3L LPT engine. After ~25K miles on a set of plugs, the car takes a long time to start, but after new plugs are in, it starts right up. I don't notice any performance improvement, but just the ease of starting. I gap them at .035".
The Trionic system puts a lot of load on the plugs. It performs a rapid set of bursts at startup time, and also performs a series of 'burnoff' bursts when the engine shuts down. This might be why the plugs seem to degrade after only 25K miles. I've run C900s for 90K miles on the same plugs with no problems at all.
