Just wondering if there's a trick to getting the coil caps off to change the plugs?
I'm starting with the far right one. It will turn easily in both directions, just won't pop off.
 

I've changed coil overs before on my Hemi and they were way easier.

I finally got it though. Had to put a screwdriver under the bolt lip and pry.

Thanks for the help.
 
I would watch out using a tool to pry these up. You are point loading at the pry point. you could possibly crack them. They do make padded tools for pulling these. But, ... I have never had one yet that I could not pull with my fingers.
 
If you are trying to get the coils out, i would spin it left a bunch of turns before you pull. Those spark plugs are threaded on down at the bottom and if you just yank them off you are stripping the threads.

Unscrew them then they should come off very easily.

Apex_shug : Use the plug tool in your tool box to get the plugs out. You should have one in there with the rubber insert in it to hold the plug and pull it up the tube.
 
The coils are just pushed down on the Plugs. There is no reason to spin them left or right very much, once they are loose. If you are having trouble gripping them with your fingers, try using some mechanic's gloves with rubber grippers on them. Or just clean the coils off and grab them with your fingers.

Before you remove the plugs, it is good to use some compressed air to blow out the plugs' access cavities in the Valve Cover (down in where the plugs are) before you loosen the plugs. This will blow out any contamination that may have worked down in there and is just waiting to fall in the cylinder (after you pull the plug) and destroy a valve seat.

To get the plugs out, you need to use the machine's plug or similar wrench. Turn them left to loosen them.
