Anyone know if there are any performance plug wiresavailable for this engine?

 

Sure, I know - there aren't any. The 4.7 is a coil on plug system, no plug wires.

 

What he said!

Now if your wanting a good plug, I use the NGK IRIDIUM'S. I noticed a difference when I started to use them. They last longer for one... I have put on over 30,000 miles on a set and when I pulled them to look at them they looked GREAT! The center post was not deteriorated one bit as you see with conventional plugs just after the first 10,000 miles.

I noticed a noticeable idle difference/quality... And I do feel they are worth MPG gains as in the fact that they just last longer... you wont get the slow decline in MPG over time as conventional plugs do... at least not nearly as quickly.

If you have any questions please feel free to contact me.
