The Vortex will fit...however, giving the problems some 2002 Z owners are having with air intakes, I would wait before installing. Seems like the 02's are needing a computer reprogram after intake installs. Not sure if the Vortex affects the 02' or not. :-?
I have Vortexes on both my Z's, but they are both 01's.
I have an '02 and my Vortex Rammer and Air Bridge was installed by Breathless at Carlisle on 8/25. I picked my car up at the Museum on 8/23 - so by 8/25 i had accumulated about 800 miles. I now have about 1,700 miles on the car with absolutely no problems except increased performance.
