Question about 2002 Jeep Grand Cherokee
Llocation of sparks plugs
For Jeep Cherokees with a 4.0 engine; (if you are standing in front of
the vehicle looking back at the engine compartment) the spark plugs are
on the left side / the same side as your battery. What look like spark
plugs on the right side of the engine are actually your fuel injectors.
On the exact opposite side of the engine block, all 6 spark plugs are
held in place with a long rectangular box (called a coil pack) that has
3 small raised boxes on it. The coil pack is the length of the engine
block and about 1 1/2 wide. There are 4 large approx 1/2 bolts that
hold this coil pack in place. There is a plug on the back end / closest
to the fire wall where you can upplug this coil pack but I couldn't
Simply, remove the 4 bolts holding the coil pack in place, lift the coil pack away from the engine block and the spark plugs are exposed. The boots that attach to the spark plugs are "fixed" in to the coil pack. Replace your spark plugs some type of using anti-sieze compound, adjust your gap, and torque to 19 lbs. NOTE: use dielectric grease on plug boots and coil pack ends of wires. can also be used on plug in bulbs.
The above answer is great but if they are platnum plugs dont bother setting gap because you usually don't get a spec anyways and you do more harm than good. The gap is preset.

Tips for a great answer:
The spark plugs in the v6 can become an involved job as the upper intake manifold. The LS uses a Coil on Plug (COP) ignition system, meaning that the spark plugs are located under the ignition coil

Locate the spark plug wires in the Cherokee cylinder head. In the 4.0 liter engine, the spark plugs are below the coil rail assembly. On the 4.7 liter engine, the spark plugs are located under each corresponding engine coil.
