Ok this one was difficult.  It might be increasing Kf (ie, changing the hydraulic permeability of the glomerular membranes or the surface area available for filtration).

Is simple, Think in the formula and the factors that afftect filtration. If you are not changing the factors involving pressure then the constant (K) which refers to the membrane properties should be changing).
Look the formula: GFR=Kf*(Pgc-Pbc-oncotic gc)
If GFR is increase and you are not changing filtration PRESSURE you must be changing Kf.

Well dilating affarent arteriole would cause an increase in both GFR and filtration pressure. Is better to say it would increase filtration pressure and therefore GFR. But by changing Kf you would affect only GFR.
