I've installed the intake system on my high millage 98 900 turbo, and I must say the results are rewarding. Spool time is much quicker, and the installation took about 5 mins with no drama.
One word of caution - If you are in California, your car will NOT pass smog due to the lack of a C.A.R.B number for the intake system. My advice - save the original airbox for smog checks...
