I would like to attempt to change the plugs on my '04 5.7 hemi but changing the plugs on the two cylinders under the brake booster make me quiver at the thought of dropping the plugs into the wells and changing the gap or worse yet not being able to retrieve the plugs. How deep are the wells? Someone has instructions on how to insert one tool at a time. What length of extension would I need to be sure I don't need two extensions withing the well? Fear and loathing in Kansas City.
