The plug gap should be on a decal under the hood that will tell what the gap is. I believe its .50 or .55 gap.

Make sure that you buy the correct type plugs(Champion RC12MCC4 or equivalent). Also it may be a good idea to have a flexible-extension for your ratchet.

To change the sparks on a 2005 4.7L Dodge Dakota you will need the following:
Note you will have to remove the air intake located at the top of the engine, and will have to move some of the coolant lines out of the way.
At the top of the engine there are 4 sparks on each side. The coils are held in place with a 10mm bolt. Undo the 10mm bolt and unclip the coil. Next pull out the coil.
Insert the socket, with extension into the spark plug hole.
Remove spark plug.
Check the gap on new spark plug, it should match stock.
tighten to approximately 25ft.lbs. (check spark-plug packaging for exact torque requirements).
repeat this process with all other sparks.
be sure that no dirt gets into the spark plug holes.

look under hood..you will see wires coming from distributor cap on top into your motor..if its an 8 cylinder there will be 4 in the back and 4 in the front.6 cylinder-3 in front 3 in back.get a 5/16 spark plug wrench and socket.you will need extension to reach back ones.if you bought new wires from parts store it will be even easier to find where plugs are located because you can compare the ones you bought and easier find the wires under the hood.the wire gets fatter as it goes into the motor.grab the fat part firmly and pull it off.boom theres your spark plugs.use your spark plug socket(5/16) with extension/ratchet and turn the plug until it comes out.do not break the plug or it will not come out.when you put a new one in screw it hand tight then 1 crank tight with the ratchet.when you change your wires do them one at a time as to avoid switching the wires up.on top of the distributor cap(where the wires lead to) there will be numbers as to what wire is for what cylinder...change plugs/wires 1 at a time dont take off more than 1 wire at a time!hope this helped!
