What is liter size of engine?

This is for 4.7 L engine. It appears jeep rwd has odd and even banks like GM and Chrysler. 1357 for driver side bank. 2468 from front to back on passenger side bank.

this job is not for a newbie. so here we go with instructions. i believe you posted under 2003 nissan maxima section for replacing plugs.
remove engine trim cover that covers manifold and valve cover.
remove ign coils on frt valve cover and remove and install new plugs
for rear bank plugs you would need to remove upper intake plenum. disconnect all necessary electrical connectors and vacuum lines. make sure you are aware where the vacuum hoses go for reinstallation.
remove ign coils on rear bank valve cover. remove and install new plugs.
reassemble all parts.

The spark plugs are located in the holes on the valve cover. If this is a v6 engine you will need to remove the plenum to remove the rear bank spark plugs.

You need a spark plug socket with a built in swivel and a extension to remove the spark plug. All the spark plugs can be easily removed through the wheel well as to the #3 plug also, the trick is that you need to use the spark plug socket to loosen the plug and then remove it by hand and also install by hand. Once the plug is reinstalled by had, just use the spark plug socket with the swivel built in to it to torque it down and take care not to break the new plugs. Good luck and yes the #3 plug takes as long to repalce as it does the all the plug on the right bank. keep me posted if you have nay more questions and thank you for using fixya.

The spark plugs should be right in the center of the valve cover you'll need to get a 6" or so extension to reach down into the cylinder head to remove them the same steps for the spark plugs on the back bank (closest to the fire wall).

The 2003 Kia Sorento with V6 has the spark plugs located under black plastic covers in the center channel of each cylinder head. Several brackets, cables, and hoses must be moved out of the way to access them. The manifold air intake tube needs to be removed on the right bank.
The left cylinder bank has coil-on-plug assemblies while the right bank has more conventional spark plug caps with sealing assemblies. The coil-packs are held with two 10mm bolts each and are difficult to get to. Use universal-joint sockets and an extension.

yes on 2.7l models intake needs to be removed to gain access to bank 1 spark plugs. it can be a pain not much room.
