Properties of tensors equivalent to the direct product of two different 4-spinors are investigated. It is shown that tensors obey eight additional nonlinear restrictions, which are presented in the Lorentz covariant form. In the context of the Dirac-Köhler theory, such a property can be interpreted as follows: if one considers a Dirac-Köhler field as consisting of two 4-spinor fields, one should impose additional restrictions on tensors of the Dirac-Köhler field, that leads to a non-linear wave equation for a complex boson field (composed of two 4-spinor fields). Instead, the use of four bi-spinor fields gives possibility to construct the Dirac-Köhler tensor set of 16 independent components. However, the formulas relating the Dirac-Köhler boson to four fermion fields are completely different from those previously used in literature. In an explicit form, the restrictions on four 4-spinors corresponding to separation of different simplest bosons with spin 0 or 1 and various intrinsic parities, are constructed..
