Abstract: We construct finite mass, asymptotically flat black hole solutions in $d=4$ Einstein---Yang-Mills theory augmented with higher order curvature terms of the gauge field. They possess non-Abelian hair in addition to Coulomb electric charge, and, below some nonzero critical temperature, they are thermodynamically preferred over the Reissner-Nordstr\"om solution. Our results indicate the existence of hairy non-Abelian black holes which are stable under linear, spherically symmetric perturbations.
