I would say that the Cobra would run better for now, but if you ever plan on getting a set of heads then maybe now would be a good time to get an intake. Be smart.

YOU COULD ALSO GET THE STREET KIT AND CHANGE OUT THE UPPER MANIFOLD WHEN YOU GET NEW HEADS BUT UNTIL YOU GET NEW HEADS AND A NEED FOR MORE AIR THE TF TRACK UPPER COULD HURT JUST A LITTLE. HAD COBRA AND WENT TO TF TRACK AND GAINED 48HP ON DYNO BEFORE I GOT NEW HEADS AND WENT TO ELD.VICTOR OH YEAH..........TF IS GOOD SHT REGARDLESS WHAT OTHER PEOPLE SAY IF, SETUP IS RIGHT YOU WILL RUN LIKE A RAPED APE, IF YOU ARE SET ON TRICKFLOW FOR SOME REASON GET THE PACKAGE THAT SUMMIT RACING HAS http://www.summitracing.com/catalogs/bigbook/2004/marapr/t138.html
your wasting your money if your heads are stock, your gonna see VERY minimal gains with a aftermarket intake, especially the track heat. ive been there, i bought GT40 intake 8yrs ago and i noticed NOTHING cause the rest of the motor was basically stock. if you absolutley have to buy a intake leave the track heat alone and get the street heat.
