I'm letting the dealer change the plugs
Here is the deal with the plugs
1- Must be torqued to spec
2- New Plugs have a special coating that negates the need for anti sieze. If you go to the plug website, they tell you "not to use anti-sieze)
3- If you take them out and reinstall them, the coating gets scratched and then you need anti-sieze
4- Anti-sieze alters the torque values as it adds lubrication. The torque wrench will read a lower value.
5- tight areas on the Ram make it virtually impossible to use torque wrench
So every 2 years or so (30-40 K miles) I'll look for dealer specials and let them do it. If a head gets screwed up, they fix it.
