How do you get to #'s 7 and 8? Seems like they're way up in there?

 

i changed to ngk v-powers at 36k, very noticable difference in smoothness and the hemi seems to build RPM faster now.. some of the plugs i pulled weren't doing so well

 

I put an old blanket on the top of the engine and lay on top of it. Pulling the wheel and wheel well liner works as well.

 

I use NGK plugs, changed a minimum of onece a year, most years, twice, depending on how hard i run the truck. Great performance with only one melted plug in 4 years. I am very happy with the NGK's

 

What would be some recommended plugs for the 4.7L? I've got 58k on mine. I pulled 1 and it was a light light brown color.

 

Two #7 inch extensions and a 3 inch extension. plus a swivel I used a spark plug socket and the 3 inch ext. followed by the swivel, And then the extensions. The socket and three inch must be disconnected before the spark plug can be removed from the valve cover well.The same as the next cylinder towards you. Started 4:30 am. with a few beers ,done by 9;30. am.

 

Well, changed the plugs last night. 4.5 hours later everything was back together. The stealership want $6.95 for the standard champion coper plugs. I bought champion double platinum plugs at advanced auto for $4.60 a plug. Truck is running great today.

 

does anyone have a diagram of the spark plugs locations on a 2006 5.7?

 

Just changed my spark plugs on my truck. I bought it used with 35k on it about 6 mos ago and wasn't sure if the plugs were ever changed. I pulled them and changed them. They didn't look all that bad, and were only slightly out of gap, but I changed them anyway for peace of mind. Glad I did also because I found two bare injector wires that look like some kind of squirrel or something chewed on them under the intake plenum. Taped them up for now, but am going to get the wires fixed hopefully tomorrow...

I started around 2:30 and finished completely at 6:30 with a lot of patience used!

 

I just changed the plugs on my 2003 4.7l. Everything went smooth enough and she started right up. However. My wife reports that since the plugs were changed yesterday when she stops to make a turn into our driveway or out of a parking lot (those were the only two instances it has happened so far) the truck just stalls out. No hesitation just stops. I checked all the vacuum hoses and all the connections and everything seems fine. Any ideas?
