drivers side spark plug

How can i get the drivers side spark plug out?? The one all the way out to the right. There's a huge metal thing that wont move at all. Any suggesstions? I'm using a 12" extension on the ratchet and the spark plug thing on the end..do i need something that can bend around the metal thing? here's a pic if it helps at all.

Nevermind, I found out how:) :) :) :) But after i put them in and took it out for a test drive i started to smell burning... :(
