We study the strong role played by structural (quenched) heterogeneities on static and dynamic properties of the frustrated Ising lattice gas in two dimensions, already in the liquid phase. Different from the dynamical heterogeneities observed in other glass models, in this case they may have infinite lifetime and be spatially pinned by the quenched disorder. We consider a measure of local frustration to show how it induces the appearance of spatial heterogeneities and how this reflects in the observed behaviour of equilibrium density distributions and dynamic correlation functions.
