hey guys i have a 05 4.7, any suggestions for plugs. i am running stock now but about to do a 60k tune up. thanks mike

 

Try nthe platinums, champions. They were reccomended when I did mine. i didn't fall for it thou. and went with the copper cores. course I have twice as many too change. : (.

 

I just did the 30k on mine ,I used the oem Champions truck drives perfect.

 

used the split fire platnums.WOW! what a difference it made.had them in for about a year now with no problems

 

are those champions? did u notice a change in mpg or just more power thanks mike

 

yes both. but its nothing all drastic on the MPG s. An my truck drives like new even on the Oem Champions. I have heard not to go with anything Platinum..

 

Exactly; but the op has a 4.7 which means he can explore different alternatives without ill results.

 

I have a 06 4.7L that just turned 60k and I'm still running on my oem plugs. I pulled one about a month ago and the tip of the plug had a light tanish color to it. It looked good to me so i put it back in. But I am still getting anywhere from 18 to 21 mpg on the hwy so i'm leaving them alone until i find some recommended plugs just for the 4.7L. If i find any info i will post it here.

 

I would change them, you can't rely on the overhead mpg reading, that it shows. imo.
