I use an 8 inch extenison with a swiel on the end then the 19 mm spark plug socket. kinda go straight down beside the fuel rail and let it enter the spark plug at a small angle..the swiel takes care of the odd angle plug hole. Works a like a champ
I always just break them loose with the socket then use 3/8 inch fuel line to unscrew them and restart them. Then torque to spec, using the ext and swiel. also coat with anti seize.
yep like he said you should purchase the extension with the swivel head.. the first time I changed mine I saved that one for last cause I thought it would be a challenge.. but with the swivel head it was as easy as the rest...
