i know this has been brought up about a thousand times but i am handicap with the search. but what are the best plugs to run in the 5.2's

 

Your going to get varied responses on this topic. Some are going to tell you to use the OEM Champion plugs, some are going to recommend Autolites 3293, and the others and going to come up with off the wall stuff.
Personally I think that you are fairly open on your plug option, but I do say stay away from platinum plugs.
Personally, I run the 3293 plug in mine, and love them, but some people have made a comment about rough idle with the AL plugs.

 

Sounds about right to me.

 

I use E3's. They idles smooth and respond well...in my humble opinion.

 

Sorry if I am jacking the thread but is on topic. Hey j415 where did you get the e3's from?

 

They have them at my local Advance...only downside is they are about $9 a pop!

 

Ooooffff. That's about 75 bucks for just plugs. Wow. How good are they? If you can't tell the difference with them then I ain't buyin em.

 

Someone else will have to chime in on that...I don't run them. Although I have considered it. They are non-gapping plugs, which come preset for your vehicle, so you leave them be until they are shot...which I think is like a 5 yr/100K interval or something crazy like that.

 

thank for the replies. just put the champions back in it and found out why it was starting rough. the cap and rotor were both shot.

 

That'll do it to you... How long had they been on there? I think mine are approaching about 20K.
