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.
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.
