Zylinderkopf Stehbolzen BARP für BMW Z3 1.9 16 V M20B20 M20B25 M50B20 B50B25

BARP is a Brand of production of high-strength studs and nuts, designed and produced in Italy, with innovative materials normally used in aeronautical and aerospace derivation. HEAD STUD KIT Our head stud kit guarantees a better seal of the head gasket, given by the greater preload impressed, and a high stability and resistance to thermal and pressure variations. The overall rigidity is therefore improved, limiting the deformations of the upper part of the cylinder block, this extending the life of the engine and increasing the resistance to the greater mechanical stresses, generated by the increase in performance in tuned engines.
