Not the answer to your question, but you'd probably have better results with a drop-in panel filter.

from every bit of information i have seen, the best intake out there is the "hybrid" style that was first thought up by Willaty. Its basically retaining your stock resonator in the fender and airbox, while replacing the torque box and maf to throttle body piping. Its generally made from an ebay short ram intake and can be done for about 40 bucks.

Theres a thread on it stickied on the top of the NA forum.

before you spend the time, $ and cut up a SRI for the hybrid, make sure that your 99 is MAF based and not MAP based. The MAP based systems dont have the problem that is solved by the hybrid intake from what i understand, so a straight SRI/CAI would work well if you dont mind the noise.

Injen CAI. I have an Ebay intake on the 07, am now switching to the Injen.
Explain:
The ebay intake worked beautifully except I hear sound of air turbulence at high engine speeds.
This is probably happens at joins of tubes that are of different diameter (The ebay intake is 3",
the MAF housing is 2.5 I think, and the throttle body is 2.75").
Injen has a built in place for MAF sensor to sit. It is of a single diameter to facilitate a fast and smooth airflow.

OBX is another CAI you could try. Its the same as the Injen CAI and should only cost you maybe $50. I've been running one for almost 2 years now and have had no problems.

You want to look for an intake that fits a MY98 2.5RS, it will fit perfectly. Not too many(if any)companies marketed an intake for our generation of Legacy but thankfully there are quite a few options around for the phase 1 2.5L Impreza which we are able to use.

With OBX he still has to use the 2.5" MAF housing came with his MAF car.
