yes its 16 plugs 2 per each cylinder, if your doing coils only the upper plugs have the coils however

It's really not as hard as it sounds. Remove the plastic air intake on top of the engine, then remove the coil packs one at a time with a 10mm socket,pull them straight up to remove. Then use a long extension and 5/8's socket to reach the spark plugs. I do the 2 plugs per cylinder then put the coil back on before moving to the next pair of plugs. It takes a vairiety of 3/8's extensions to work around and under the obstacles. 1st time I changed them on my truck it took about 2.5 hours total.

Wow...thank you guys this is very useful everything makes sense now. I will feel more confident doing the changing of the spark plugs. Can anyone suggest a good brand for a HEMi , Ive been told to try Autolite, NGK, Splitfire, E3...?

There is no need to pull the intake off. The best way to service the rear most cylinders is by removing the inner wheel well and going in through there. Good luck getting the plugs that are covered by the brake booster with a million universal joints and extensions. Dont use any anit-seize agents on the plug threads and be careful not to cross thread the plug in the head being as its aluminum. Also, if my memory serves me correct, the newer hemi ignition systems are a non waste spark system, which has a coil per two cylinders on the same bank as opposed to the old design, so two plugs under each coil. As per plug choice, you should use the plug style that was chosen for that vehicle. Going with a colder range plug for 'better performance' id erroneous and has a negligible gain if at all.

Hey guys, it is even easier than that. I know this post is from a while ago, but I just changed the plugs out on my 2008 5.7Hemi Ram 1500. The only real issue plugs are the ones under the master cylinder. Here is what I did and it took no time at all. Remove all of the coil packs on that side of the engine. It helps with access to the plugs in the back. Not sure if you need to, but label them so that they go back in the same place. Then you will need a spark plug socket, 3/8" swivel, and 3/8" 3" extension. In the order listed, place the socket, swivel, and extension in the hole and then attach the wrench. With a little muscle and arms that can twist like a pretzel, you should be good to go. I would also recommend a small step ladder and an extendable magnet to get the plug out of the chamber if the foam inside your socket no longer works. This scenario also works for the last two plugs on the drivers side. So no need to remove any fender wells or intake manifolds. I would however on the passenger side, remove the air cleaner cover and pipe to make it easier to get to those plugs. Those are pretty straight forward too.
