StangMods.Com has them for $289.00. I would love to know if the T.B. makes a difference you can feel from a dead stop. I did a K&N CAI and a Flash Tune on mine, and it made a noticeable difference at higher RPM's, but otherwise the power difference is negligible. I am dissapointed so far with trying to gain more torque from a dead stop and am considering a rear end gear change to a 3.73.
