High End stud kit for the cylinder head for all 2.5L TFSI as build in the Audi RS3 & TTRS.

BAR-TEK® studs have a hexagon socket to screw in the stud bolts. By a cone on the block side of the bolt, these are based on tightening the nuts not on the thread flanks, but in the bore of the thread in the engine block. This support protects the thread with frequent assembly of racing engines.

All threads rolled for maximum strength
with neck cone for preloading for optimal distribution of forces on all threads
Hexagon drive for easy installation
Tensile strength over 1800 N / mm² (270,000 psi)
