I took my 2007 Dodge Nitro R/T (4.0 engine) to my Dealer with a bad engine miss (PO 302) expecting an expensive repair to replace injectors, coil pack and plugs. I was surprised. Tech swapped plugs and coils and found a bad plug in #2 cylinder that followed to the moved cylinder and recommended a tuneup only. The labor was $260 and plugs were $66.90 (#11.15 each)

Yes these MOPAR plugs SZFR5LP13G can be found on Amazon for less but comments may be important.

Mopar SZFR5LP13G Spark Plug

Mopar spark plugs come pre-gapped.

Don't order anything but exactly came in your car. Mopars are very temperamental and will cause misfires and check engine lights if other plugs are used.

NOTE

Changing Nitro Plugs 4.0L


I have attempted in separating "Changing Nitro Plugs 3.7 & 4.0L" into two THREADS. One for each engine type, since there are differences mainly the requirement of removing the intake manifold on the 4.0L (R/T) engine to end any confusion. I did not remove the posts concerning the 4.0 engine from the original thread but did mark them in RED.

Hopefully this will help.
i just did the plugs in a2011 4,0 I left the seven manifold in the manifold Ibacked them so they threaded into the manifold I also did not remove the throttle body frome the manifold
