I just did my spark plugs last week on my 07. I found that a universal joint socket will be your best friend with the 2 outside plugs because the extention used, or socket wrench itself, hit the frame.
Thanks for the input and the sarcasm! haha. I put the spark plug socket in just to test (no ratchet or room problems) and it wouldn't fit. I eventually used a regular socket and a magnet to get it out because of the lack of space.. just wanted to make sure nothing was warped since it was only the one cylinder
