I have a ram with the 5.9, does anyone know what you need to gap new plugs to?

I think it depends on what year your truck is. My truck has a sticker on the front radiator brace right in plain sight you can't miss it. It has a diagram of the vacuum and emission system as well as giving the plug number and gap that you need to use.

My Computer at Checker autoparts says .040, but you should go by your emissions sticker.

94-97 rams =.035, 98-current = .040
