What plugs?

[aquickv6]

What plugs should I use for my GTP? I have the CAI, 3.4 pulley, and the 180 T stat, no computer mods, and stock exhaust. This is a Florida car, street only. Thanks.

Autolite 104 copper plugs.

Thanks, Is that one range colder than stock?

 

[Bluto]

No its two ranges cooler. That's what I use with my 3.4.

i use autolite 605s(one range colder)....i personally don't think you need 2 ranges colder
you can't go wrong with either though

Autolite 605's (copper?) Will these last as long as the factory AC's

Are they supposed to be better?

You can get either plug in copper or platinum ect but usualy we all run copper. They are cheap. You should change them much sooner than the factory plugs. Some guys recomend every 10,000 miles.

I change the 104's every spring. I run them hard in the summer. I see a lot of track time.

If you do dome hard runs it doesn't hurt to check them every couple oil changes if you are worried.
