Warped extra dimensions with bulk fields provide a natural solution to both the gauge hierarchy problem and the hierarchies in fermion masses and weak mixing angles. On the other hand one now has to deal with flavour non-diagonal couplings which make FCNC studies interesting.
In this talk a model with enlarged bulk gauge group SU(3)c× SU(2)L× SU(2)R× U(1)X× PLR will be discussed. In this framework, the inherent custodial symmetry allows the Kaluza-Klein particles to be light enough to be accessible at the Large Hadron Collider, but still guarantees consistency with electroweak precision observables. Especially, I will present the results of our recent study on rare K and B decays. In addition to the SM one loop contributions these processes receive new tree level contributions not only from the heavy Kaluza-Klein gauge bosons ZH and Z′ but also from the Z.
