Erm, that looks ok to me? Light brown powdery deposits, clean thread past a certain point? No sign of oil burning or leaking.
What do you think is wrong there?

How to read your plugs
As you change your plugs, it's a good idea to look over your old plugs to get an idea of how your engine is running and to help asses what your next plugs should be. Mostly your making sure your in the right temperature range, and that everything is consistant in all four cylinders.
-light brown/tan/gray in color they are the right heat range and A/F ratio
-white and you want a colder plug, likely running too lean i.e.: too much air, not enough fuel. (too much boost...)
-black (Majority of faulty plugs fall into this category)
---black and dry, you want a hotter plug
Dry fouling refers to the accumulation of carbon on the firing end of the plug which decreases the insulation and finally leads to miss-fire.
---black and Wet, you want a hotter plug
Wet fouling refers to the black and shiny state of the firing end covered with carbon and fuel which decreases the insulation causing the engine to mis-fire
-Often simply need to simply drive harder, add a freeway run into your short commute or something (quit being a spode and DRIVE the darn thing)
-The fuel setting (A/F ratio) is rich (chipped often run slightly rich)
-dirty air cleaner elements.
-Idling for a long time.
-The heat range of the plug is too cold (using a MBC and no chip(stock))
-reddish could indicate fuel system degredation troubles,iron content, rust
this was in the FAQ's part

That electrode is a precious metal version, platinum I think? They come like that brand new. It's what went into mine as standard fit.
And most plugs now come pre-gapped, you can damage the plug if you try and adjust the gap.
