  We compute the renormalization factors of four-quark operators needed for the
study of $K\to\pi\pi$ decay in the $\Delta I=3/2$ channel. We evaluate the
Z-factors at a low energy scale ($\mu_0=1.145 \GeV$) using four different
non-exceptional RI-SMOM schemes on a large, coarse lattice ($a\sim 0.14\fm$) on
which the bare matrix elements are also computed. Then we compute the
universal, non-perturbative, scale evolution matrix of these renormalization
factors between $\mu_0$ and $3\GeV$. We give the numerical results for the
different steps of the computation in two different non-exceptional lattice
schemes, and the connection to $\msbar$ at $3\GeV$ is made using one-loop
perturbation theory.
