You can also add some OTRCAI(over the radiator cold air induction) from Oz. Protorque and G&D seem to be the most popular with gains of .3 and 2-3mph being the norm.

Also TB bypass is free for the '04. Just reroute the lines. The '05 doesn't have coolant flowing in it so you don't even have to worry about it.

The catch can price from AMW doubled! 180 or so for the can. Work of art but shouldn't have doubled in price as of 8/1 or thereabouts.
