Default 2007 GXP GP - K&N

Is the K&N cool air intake worth buying? I drive 140 miles a day. love my HP - any more is a plus. But i am really interest in fuel economy. Now i get about 23.5 mpg (most of my drive is I85 (Atlanta).

Has anyone conbined the intake with a tornado?

or is just a tornado the way to go?
