Well, on my MY00 uk car I dismantled the airbox and moved it to one side and unbolted the water bottle and moved that out the way too.

Now you can sort of get to the plugs. If there the same leads to mine I had to twist them 90 degrees and give them a fair yank - don't do this with a hot engine I cooked my hand quite nicely getting it stuck between head and lead!

Using 1/4 inch rachet set
Think its a 17 (? smallest one I had) plug socket and a small extension so it just pokes out the end and fit the rachet to it. If the plug socket has a little rubber gripper I'd take it out when re-fitting or the socket can get stuck on the plug.

Just take your time and you'll be fine. If the oil hasn't been changed for a while it might be worth doing as you'll not have pressure build up when cranking.

Do the right hand ones (looking from front) from underneath, much easier...
Left hand ones from top.
Fiddly but not difficult.

You'll need to use a 3" extension and a 14mm socket to get the plugs out, we had to put the plugs back in to go and buy a 3" extension as most socket sets have a 2" and 4"X 1/2" extension and thats on our old 94 wrx. You'll need to remove the air box and washer container. Very easy job and only takes about 30 mins.
Also you don'y need to come from under the car to change any of the plugs, just go in the normal way.
