Does it really matter what spark plugs you use and wires for performance, I am not very knowledgeable on this subject

 

You don't need to replace wires/coil packs unles they are bad.

As far as plugs go....Basic copper plugs every 30kmi.
Don't do fancy plugs..These engine's aren't designed for them although you may not have issue's, Chrysler suggests copper for a reason. Plus they are only $2 per plug.

 

^^ what he said

 

I put split fire platinum plugs in my 4.7 and it runs like a screaming banshee.I'll buy them again for sure.

 

Alright thanks, i just hear all these different type of plugs and i really just wants whats best for my truck and if its copper plugs for 2 bucks then great

 

NGK's work great and they are cheap. like stated before the only time i had to change a coil pack was when i was getting a constant misfire from cyl #1 and plugs and wires didn't fix it. the coils are spendy too

 

Champion or NGK V-power plugs. The rest are a waste of money. New plugs almost always run better than old ones!!

 

Just put NGK Iridiums. Truck runs so smooth I couldnt believe it. Expensive though about $7 a plug.

 

Anyone try out the E3 plugs?

 

I assume you are talking about the E3's for a 4.7?
Because its ridiculous how many times its been said on here that the basic copper plug, Champion or NGK V Power, is the best plug for the Hemi. You spend 7-8 bucks or more for 16 of anything else your just wasting your money.
