Spark plug change
Hi, I am getting ready to change spark plugs on my 03 v10 the plugs have about 75k on them, any tips and tricks to get the job done will be greatly appreciated, am a little scared to tackle this task due to reading about the plug issues these motors have

The only plug issues the ‘03 V-10 might have is them leaving the heads all by themselves………but by ‘03 I think that earlier issue was corrected with more plug threads in the heads. Later on the early 3V motors had issues where the 2 piece plugs liked to break when removing them. You shouldn’t have any issues pulling your old plugs on the ‘03, just be sure to torque the new ones to at least 26/28 ft/lbs to keep them fully seated. On mine I found a decent wobble socket with a 4” or 6” extension made access much easier. Also be sure to install new rubber boots along with the new plugs.
