K&N FIPK for C5

I just picked up a 99 C5 last night.
Anyone here using the K&N FIPK? Any before after dynos? Pros/Cons?
It looks like a nice piece!
BTW I LOVE this car!!
Eventual mod Plans are:
3.42's
TCI 3000 stall
K&N FIPK or ziptie mod with Z06 airbox
Plugs (TR55)
LS6 intake
Z06 catback (If I can find one)
