Plenty of posts about this but it's not hard, it's just a pain in the **** for some of the plugs. Make sure you have a good 5/8's plug socket (1 with the rubber piece inside of it), a couple different length socket extensions, and a socket u-joint is a must. It'll take you several hours doing it the first time with standard tools but you may feel you can do it quicker the next time after the first experience.

Auto Zone can tell you which plugs if you just give them your year, make, model, and engine size. Just tell them you want the OEM copper core Champion plugs and the other info and they'll know exactly what you need. Should be less than 2 bucks each and you'll need 16 of them. You'll also want to put anti-sieze on the new threads and dialectric grease or plug goop on the tips when installing them. And the plugs themselves are supposed to be torque'd to 15 ft lbs +/- 2 lbs so a torque wrench would be needed as well. For more specifics, look around, you'll find plenty of info.

 

ok good got all the tools, now just gotta figure the plugs for the 4.7. i went to championsparkplugs.com and found what i need, just recommend what ones you think i should get

Rc12mcc4

 

damn!! big mistake on my part thought they would of been different due to the motors being different. Sorry JOEHEMI shoulda done my research a little stronger

 

When I did mine last I had a BL also and it does help.......... ;-)

 

i do have the body lift so i am excited on that part of being easier

 

yeah all i used was a 5/8 spark plug socket, a 3" ext, a 6" ext, and a 10mm socket for the coils. not sure if you need that for the 4.7. i didnt use a swivel joint and had no problems. def do the back drivers side first just to get it over with.

 

I didnt need a swivel but i used a ratchet that bends at the end in any direction and it made it easier. I hate a damn binding swivel.

 

The plugs are slightly different. The hemis take the RE14MCC4 with the .045 gap while the 4.7s take the RC12MCC4 with a .040 gap. Also, I did what jes did and just used a ratchet with a swivel. The universal I had was slightly too big to fit in most areas but the swivel head ratchet worked great.
