Was wondering if anyone here could tell me how many miles should the spark plugs be replaced in a 04 ram / 4.7L?

Thank ya

 

every 30,000 is a good time to change them on the hemi i believe. I think you can get by going a quite a bit longer but not sure how much...someone will chime in.

 

I think yours will go longer. Check your O/M. You might be able to do the 100K thing.

 

I did plugs in my 2002 at 95,000 miles. They were in pretty good shape, but ready to be changed. I towed with that truck a dozen or more times a year. It wasn't a hard job.

 

I think its a 60-100k thing but I still change mine every 30k, better safe than sry and its cheap, so why not?

 

My 2005 maintenance schedule book says every 30k.

 

every 30k miles guys its horrible for your gas milage and internally as they gunk up and dont fire correctly if you go so long....why is it ppl think i add gas and change my oil my vehicle should never break down....its not like that at all....and i get it all the time im not sayin the op thinks that im just making a statement

 

8 plugs @ 30,000 miles. 4.7 and HEMI
