I am going to be replacing my spark plugs on my 03 dodge ram. I took a look under the hood and saw that the spark plug wires go into some type of metal boot at the spark plug hole. how do i remove this boot to get to the spark plug. Is the 5.9 hard to change plugs on? thanks for the help

 

DON'T remove the metal heat shields! They do come off but you will hate yourself in the morning or you may just hate yourself now (Rodney Dangerfield). Pull on the top of the spark plug wire & boot (where the wire meets the gray boot) and twist. Only remove one wire at a time and make sure you gap the plugs and install the metal spark plug gasket ring in the proper direction (directions on the spark plug box). And yes, your back is going to be sore tomorrow even if you use a small foot stool.
