Okay, i have searched and found most of my answers, i know im going to go with motorcraft plugs, and read that the gap is around .054. only question left that i havent found the answer for, is can someone tell me what i should torque them down to? i dont have a manual for my truck. its a 1997 4.6

please and thanks in advance

 

28' lbs. You don't go buy the the manuals specs. Manual spec is 11-15' lbs. That's too light for these heads and chamber threads, they come back out on yuh. So 28' lbs, that way they'll retain their value...or stay tight.

 

thank you very much!

 

No problem
