It will be interesting to see if it works or not, if you go to the sellers web site
RadiatorsUs they don't list the SVX as one they support and actually the only Subaru they list is the Forester (1999-2002).
With the seller of the silla radiator, there website lists one for the SVX (and we know it fits, as it's been used already)
If someone does order this radiator, post and let us know if it works or not.
