Reliable my ass...I'm working from home today...
Backing out of my garage yesterday afternoon the idle became unstable and I threw a P0300 random misfire code. I pull the plugs for inspection and above is what I found; the insulator had broken and dropped covering the electrode. Luckily it didn't break free and fall down into the cylinder! Nobody that stocks X plugs was open yesterday, and I was a newb and threw away my factory set, so the car sat until this afternoon when a local shop (Evolution Dynamics) stopped by with fresh set for me. Pathetic for a $60 set of OEM NGK plugs with only 11k miles on them (replaced @ 25k) if you ask me. The problem is, there doesn't seem to be any good alternatives as the only choice are $30/each HKS plugs which people seem to have knock issues with.
I haven't driven the car yet, but it seems to be idling stable and normal with the new plugs.
