I feel your pain

I just finished changing spark plugs in a 2003 V6 Mustang and my wounded hands are the evidence of a rough time. The back plug on the passenger's side is a son of a gun. The EGR pipe and an a/c hose make it very difficult to access this plug. I couldn't remove the EGR pipe because the nut securing it to the firewall end of the pipe is inaccessible. I have a variety of sockets, extensions and spark plug swivel sockets and it was still hard to change that plug. I ended up using a extra-long deep socket on the plug and turning this socket with a long, offset 3/4" box-end wrench.
