They are under the coil packs. The rear three can be replaced easily with a male 25 torx socket and a 5/8 plug socket. However, the front 3 require removing the air intake plenum first. There are several sensors that need to be unplugged. Also the throttle linkage needs to be unhooked. Several bolts around the edge of the plenum that hold the oil fill, dipstick, support bracket, etc. Also the intake hose clamp needs to be removed. Finally there are seven bolts that hold the plenum to the intake. These 7 bolts have loctite on them that needs to be cleaned off and new applied during installation. Take your time and the plenum comes off easily. Be especially careful not to drop anything down the intake once the plenum is removed. The good news, Chrysler says 70,000 between changes so you don't have to do it very often.

Here is a link to dl the manual as I was unable to find a diagram. Hope this helps some.
