Whats up guys and gals, I have a question:

Is changing the spark plugs on our 4.7L engines a do-it-yourselfer? I have almost 65k on the truck, and I havent changed them yet, am thinking it is about time.. Is there a lot to it? I am an experienced Ford mechanic, (I know.. but now I drive a dodge) and have a ton of experience with 4.6L fords, and of course the all popular 5.0 engines, but haven't done much accept exhaust work and intake to my new dodge... Anyone have any pointers? Which plugs should I use? Should I get new plug wires as well? Thanks in advance, sorry I'm such a newb when it comes to the Mopar stuff..

 

Welcome from the dark side BgBluRam, glad to see you've finally seen the light. I have the same engine, but had a dealership change mine. Maybe one of the others will provide you with the info you're looking for.

 

its completely do it yourself it wasnt hard. the spark plugs enter through the top of the cylinder not the side. if you look at your intake manifold you'll see eight plastic tube looking things with wires connected, it just unscrew the bolt that holds those down and they pull right off. then they change like normal. the spark gap is set at .040

 

is that the same idea for the 5.7l hemi.

 

Thank you so much. I know better than to come on here and ask a question without even poping the hood to look for myself. Are there any specific plugs that I should use? I would like to use the best, any help would be appreciated! Thanks!

 

I have the 4.7 in my truck and my JGC. I just changed the plugs in my JGC. I took my time and it took me about 1.5 hours. Mainly cause I was messing with my little girls at the same time. I used the Bosch Platinum, they come pregapped so you don't have to do anything to them. Just pull the coil pack off, pull out the old plug, use some anit sieze, install the new plug, install the coil pack, and your done. The Bosch have been running great in my JGC. I'm sure they will do the same for the Ram. Good luck.

 

Any specific plug to use?? Was thinking either Bosch or Autolite...

 

yah, i've always used Bosch plugs in my other rams they seem to run just fine...not much to doin plugs on the 4.7, got take off the 10mm nut holding down the coil packs and then they just pull right off, it can easily be done in under 45 min, just my $.02 worth

 

OK cool, that's what I'll do then.. My truck has 65k on it, does that sound like enough mileage to need to change the plugs? I used to change the plugs in my Mustang GT about every 30k..

 

yah, the 4.7 plugs need to be changed every 30K
