Changing sparkplugs on the 4.0 Pacifica
Looking at the configuration of the motor I realize there must be "tricks of the trade" needed when changing these plugs.
Could those guys experienced in these techniques please share them ?

On the 3.5, I have heard the intake manifold has to come off. I have never done this maintenance yet. It might be the same for the 4.0

When the spark plug has a single or double platinum tip, the recommended service life for normal driving conditions per schedule A in this manual is 100,000 miles (161 000 km). The spark plugs have a recommended service life of 75,000 miles (121 000 km) for severe driving conditions per schedule B in this manual. A thin platinum pad is welded to both or just the center electrode end(s) as shown in.moe
