I've got almost 170K on the plugs in my car. Was dreading taking everything
apart to get to the plugs but after doing the thermostat that required
pretty much stripping the engine, I'll replace them soon. It does miss on
acceleration sometimes. The widening spark gap does put a strain on the
driving electronics.

Was written up in this forum a few years ago about what plugs to use. I
would normally go with Bosch but consensus of opinion was to go to a GM
(alas, no more saturn dealers) dealer and get the OEM plugs.
