This will take 1.5 to 2.5 hours; depending on your experience and breaks. You will need:

• Standard 3/8" ratchet
• 12" extention (for the easy ones)
• 2" extention
• 1" extention
• 5/8" sparkplug socket
• 5/8" deep socket
• Standard 1/4" ratchet
• Standard 10mm socket
• Slotted screw driver
• Anti-seize
• Sparkplug gapper

Start by taking out the air cleaner and elbow; all you will need is the slotted screwdriver to untighten the clamps on either end of the elbow, disconnect the mass airflow sensor, and the air cleaner just lifts out. Be sure to cover the throttle body so something doesn't accidentially fall in.


I choose to do the harder side first, the driver side. (Note the oil around the oil fill neck; this is what happens when you let someone else change your oil)



Back out the 2 bolts holding the coil pack in (note that they are just snug, not insanely tight, return the favor when you reinstall them) and remove the wireharness that plugs into the coil pack. I forgot to take a photo of the coil pack out, but there is 2 black pieces of rubber about 4" long that come out with it. They house the wire that connects the sparkplug to the coil. You will have to take several of these out at angles. The most difficult one to remove is the passenger side next to the firewall.

In this photo I have already dropped the sparkplug socket in the hole. For many of these you will have to work your tools in pieces, hence the reason for a 2" and 1" extention.



Put in your 2" extention and then your 1" extention (on some of these you can put the socket in with the 2" extention attached). Attach your ratchet and remove the plug. Be sure not to bust your knuckles, it's tight and there are a lot of sharp spots to remove skin on.



You will have to remove the plug and tools out in pieces









Be sure to put anti-seize on the threads so you won't have a frozen plug when you do this again in 30K miles. Gap each plug to 0.043, only 3 of the 16 were correctly gapped.



Be sure you put the plug back in with a standard socket, or you won't be able to get the socket back. Put each plug in by hand and try to not let it smash (fall) into the hole.



It's easier to do both the driver side and passenger side "firewall" spark plugs if you leave the coil packs off the one before.



Now on to the passenger side. This side is a breeze, except for the back two plugs. However, Dodge did a nice job routing the heater hoses and made the retaining clips easy to unlatch. You will want to open two of these clips, the one on the firewall and the next one closest to it.





Here's all 16 plugs



Most of them look like this close up










Notes:

• DO NOT use a locking extention; you might be able to get it in, but won't be able to get it back out
• DO NOT use the socket puller to put the sparkplug back in
• As for correctly tightening the new sparkplugs. I don't know how to describe it other than you want to feel the crush washer (also called the gasket) crush. Hand tighten each plug (with just the socket and extentions) then use the ratchet. DO NOT OVER TIGHTEN!

Disclaimer:

• I'm not an expert, just an idiot with tools. Call your dealership with any questions with possible warranty concerns; they'll try to talk you into bringing it there so they can spill oil all over your engine too. Your results may vary

 

Are there 2 plugs under each coil pack? I thought the second set of 8 was below? If the first is true heck I will do this, my only fear is if there is an issue with a frozen plug and it strips, wont be warranty if I do it, but if they do it then it will be their fault. I would be curious to pull a plug after the dealer does it and see if they use antiseize I am told they don't for some reason it's not necessary maybe because it stays clean and dry.

 

Correct, there are two plugs under each coil pack.

 

Great write up! Thanks for taking the time to do this.

 

Did you change these at the recommended 30,000 mile interval?

 

Thank you caseykerner
MMagee82 I changed them out at 30k

 

Thanks for the info, and I have to agree with caseykerner this was a good write up with some excellent pics! I am coming up on 30k miles fast so I will be referencing this material soon

 

What type of plug did you use?

 

OEM, which is NGK.

 

Thanks for the info!
