The hemi's and newer 4.7's have 16 plugs. they have them on the intake AND exhaust side

 

cant you just hand tighten them hard. like what the difference hand tight you and your friends and 15 pounds??

 

you can get by with hand tightening them. The biggest thing is you do not want to over tighten them or else you'll strip out the threads.


also, like 04ramslt said, all the hemis have 16 plugs and the 08 and newer 4.7s have 16 plugs. The goofy thing about the new 4.7 is you have two banks of plugs. One gets replaced like every 48k miles and the other bank gets replaced every 96k miles. You'll have to check the owners manual to make sure those specs are right. Also, the top bank of plugs are set to different gaps than the bottom.

 

Installed NGK V-Powers a couple of weeks ago. I use them in all my cars.

 

Well I have a little bit of a dilemma, when doing a recent tune up i came upon plug #8 and found it to be seized up. The last thing i wanted to do was snap it off in the head, so i sprayed some penetrating oil on it and just left it to sit hoping the heat from the engine might pull the oil into the threads and loosen it up. Does anyone have any suggestions as to how to remove it if the oil doesn't help. By the way its a 2002 Ram 1500 with a 4.7L. Ive been told some horror stories by my mechanic of customers needing to send the Engine heads out to machine shops to be professionally removed costing well over 1400$.

 

will be changing soon, going with the NGK

 

i guess im just going with the stock replacements. im only running a v6 and not really worried about any performance gain or anything.

 

i jus got some double platinum champions, wutdo u think they should b gapped @?

 

changed my plugs for the first time at about 80,000 miles and they still looked clean. I replaced them with OEM champion.

 

I'd go with what is recommended on the packaging the plugs came with.
