It ended up not being too bad...but you can't do the pull the cap and hang it to the side while you swap the wires one at a time to the new cap. You have to pull everything out and then put one wire in at a time.
Have a fireing order diagram handy. I have a laptop out in the garage so it was no big deal.
You have to pull the air cleaner housing also.
On that note...who the fukc designed a air filter housing that you have to remove to check the filter?
Oh, and the PO of this Ram must not have ever heard of anti-sieze because I thought I was going to bust the fucking plugs off. Had to crack them loose with a 1/2 inch breaker bar.
