OK guys, here it is. A DIY on how to change the spark plugs in your 3rd Gen Hemi Ram.

What you will need:
16 New Spark Plugs (preferably copper)
Basic Ratchet set
A few different sized extensions
Spark Plug Socket
Anti Seize

To start, park your truck, let it cool off, and open the hood.

Note: Under my hood is dirty, dont let yours start looking like this.

Next, take off your intake, and disconnect your battery.

I like to start on the passenger side plugs first, because they are easier. Locate your first coil on the passenger side, and remove the 2 bolts holding it in place with a 10mm socket.

then simply pull out the coil and also the plug boot for the plug next to it. (note, i have shorty wires, so mine might look different than yours, the process is still the same though)

Now, attach your plug socket to an adequate length extension, and remove the plugs.

Now that you have the first two plugs removed, grab your 2 new plugs, properly gap them with a gapping tool, apply a little antiseize to the threads, and put them in in the exact opposite as you took the old ones out. once the plug is snug, tighten it down approximately 1/6 of a turn. replace the coil, and tighten that back down.

Now, move on, and do the same exact thing you just did to all the rest of the plugs.

Once you get to the hard to reach plugs, you will no longer be able to use your 1 long extension. Instead, use several smaller extensions, and place them into the hole one piece at a time.

Now for the last 2 pairs of plugs, the dreaded 4 under the brake booster. OH NO! Actually, its no big deal. Just take off both coils, and the coil next to them. Be sure to keep them in order and dont mix those 3 up. Then just slip your tools one piece at a time into the spark plug hole. Socket first, then a medium length extension, then your ratchet. Loosen the plug, remove the ratchet, pull up until you can get a finger on the socket, remove the extension, then pull the socket with plug attached out of the hole. No big deal.

IMG_1217.jpg

In the above pictures, you can see that I have a full sized 3/8" ratchet under the brake booster. I have plenty of room to work, and to turn the ratchet. Those last 4 plugs may look like a daunting task, but as long as you put one piece in at a time, its a piece of cake.

Total time for me to complete the entire plug change was under 2 hours.

A small magnet to pull the plugs out can be easier then trying to keep the plug in socket if you dont have a socket with the rubber boot. Good write up there bud.

I need to change mine out, I was planning on changing them out tomorrow. But I'm kinda scared of screwing something up. Is it really easy to screw something up when changing them out??

nah, you dont need to worry about anything. Just make sure you use anti-seize when putting the new plugs in. Other than that, it's straight forward :)

If you are changing like you are supposed to every 30k no point in wasting time with antiseize. If you want to go ahead though. It is actually easy just a bit of a hassle just make sure you have different length extensions and it is a breeze.
