Warning, parts will be expensive. Check the SRT-6 part of the forum for some of the better known places. But, I hear Renntech is good. Mostly mods are pulleys for superchargers, but I think they may have air intakes and some supsension bits. A quick inexpensive drop filter change to a TrueFlow airfilter (2 actually) might do better than a fully upgraded air intake...... Be happy with your stocker, at least until warranty is up. If that part cost doesn't get you, the labor might... Best to be a handyperson as well.... Crossfires' aren't tuner cars like the SRT-4.
