If it is the 5.7 hemi there are 16 plugs, 8 are fairly visable and 8 are under 8 coils. the visable ones are removed with a 5/8 sp. plug socket and 4-6" ext. and ratchet. The ones under the coils are removed by first removing 2 -10mm cap screws. The screws are "captured" in the coil frame so u won't drop them into the plug holes. Note to self...upon removing the old plugs, be extra careful not to drop anything in the plug holes b4 u put in the new ones. Pretty sure the gap was 045" but ck when u buy the plugs.
