I'm changing the plugs in my 03 Ram QC w/ 4.7 this weekend and wondered.......is there a specific amount of torque for tightening the spark plugs? I've looked all over for some sort of repair manual and none of the usual places have one. Guess it's time to try ebay.

 

I usually do finger tight, then a half turn/ The book i have shows 20 ft/lbs. That's out of the 04 Ram shop manual.

 

Been doing finger tight, 1/2 turn like MoparTodd says and never had a problem on any spark plug of any kind. Also, be sure to use a little anti seize and some dielectric grease in the plug boots. Depending on miles maybe you should consider new wires. Just a thought

 

I agree with both of the above. I know I should torque, but I've never really trusted the torque wrench and usually just go by feel...it doesn't take much. If you overtighten, you'll only make that mistake once. Helicoils are no fun for stripped out heads. The antiseize and dielectric grease are things that get forgotten about a lot, but sure makes it easier next time.
