Same as the afm from the sti v3 and 4, allows you more headroom when modifying for more power.

thanks very much m8
seen an sti version 4 earlier,asked owner to pop the bonnet low and behold same maf sensor,so at least i know what it's off now,because wrx in dealer was showing a different one,to the one i have think it may have been tinkered with in japan before it came over as it has roller bearing turbo(IHI)or are these standard??
