After a short introduction to FCNC processes and models with universal extra dimensions (UED), I will discuss the impact of the Kaluza-Klein modes on the most important FCNC processes in a five dimensional model of Appelquist, Cheng and Dobrescu. The discussion will include the Unitarity Triangle, rare and radiative K and B decays and the ratio epsilon prime/ epsilon. The virtue of this model is the only one additional parameter relative to the Standard Model: the compactification scale that can be as low as 250-300 GeV. Consequently possible enhancements and suppressions relatively to the SM can be uniquely determined.
