Open the hood, remove the coil retaining bolts, unplug the coils and pull them straight upward, use a 9/16" plug socket and remove the spark plug, install in reverse order. Tighten them to 34 Nm (25 lb-ft). I would recommend a torque wrench since this engine tends to blow the plugs out at take the threads with them which really makes a mess.

Locate your ignition wires that go into your engine block remove the wires without ruining them then find a socket that will fit the spark plug they sell spark plug sockets if you don't have one then put the socket on the wrench and make sure you have the wrench to go the right way so you don't overtighten the spark plug that is already in place remove the old plug and gap the new one then install it making sure to not overitighten then replace the plug wire and do this until all eight plugs have been changed

they are suppose to be OK for 100K miles , but if you still want to change them u need an 8mm socket to remove the coil on top of the spark plug , and that is exactly its name (coil over plug) now then you can gain access to the plug , by inserting a 9/16 plug socket , and a ratchet extension, insert he new plug using a piece of vac *** hose to drive the plug back in the cylinder head . don't use the socket or you will be taking chances of ruining your cylinder head . then you will need a major restoration of the cylinder head , that is why ,if i was you I will let a mechanic do this for you , cause you can ruin the engine just cause you want to chance the plugs , see what I'm mean. best regards.

You have to remove the coil that fits over the plug. Once that is clear, then use a deep well socket and remove the plug.
With a 05 truck, it most likely is still under warranty, and even if it isn't, the plugs should be good for 100K miles. good luck.

C.O.P AKA coil over plug, your going to have to unhook the gas line off the drivers side to get to the back two and the passengers side your going to have to remove the power box on your firewall. It is a pain in the asss but better taking it to a shop and coasting you 200 dollars.

Take it to the dealer man, If you screw up, Your engine could take a poop. Changing the spark plugs is hard to do, only certified mechanics should do that.

pretty simple actually with a few standard tools.
with engine dead (not running) and cool enough to touch with bare hand...
pull the front spark plug wire off the front spark plug. take a deep socket (that fits the hex on the base of the plug) and a ratchet ... turn CCW the first plug out. replace with a new plug by reversing this process.
do one at a time: pull wire, remove plug, install new plug, re-install wire. this way you don't have to worry about which wire goes on which plug and totally screwing up your firing order.
pretty simple, eh?
EDIT: that is for a simple engine.
