Use zip ties if you break the plug wire guides. Mine where brittle, not because of my brute strength.

 

Bump for plug #3!! I have no idea what you guys mean by putting a wrench at the end of the socket....could someone explain cause I cant get it !!! What do you mean by Turning the steering shaft??

 

Some Sparkplug Sockets have a Hex Head on the end of them which would allow you to put an open end or box wrench on the socket to aid in the breaking loose of the sparkplug........
