The scoops on the 99+ cars are held on by plastic push pins and double stick tape. There really isn't a need to pull the interior panel off to remove it.

No there really isn't a kit to make the scoops functional. Early SN95's (94-95) did have a functional scoop. It would vent air through a channel and dump it inside the wheel well. Didn't really do much so Ford phased it out around mid-95/96.
It won't really help anyway. The stock GT solid rotors blow ass in terms of performance.
