Sternmutterersatz

Star nut replacement kit for defective manifold threads on BMW Motorcycle exhaust headers

Boxer Motor

The exhaust thread on the cylinder head of your bike is ruined?

Simply clean the remaining thread from residues and mount the adapters. Tighten the screws provided with the help of a 5 mm Allen key and there is a perfect hold again.

The scope of delivery always refers to a whole bike. This means 2 sets for a boxer and 1 set for the single cylinder.

The adapter clamping ring is 2-piece and threaded and therefore clamps securely onto the remaining thread remnants, no matter how minimal they may be. Of course, it also fits on an intact thread without damaging it. (Force and form fit)

Currently available for manifold threads:

M45x2    M48x2    M52x2

M45x2 e.g. for

* Since the mating flanges have to be pushed over the manifold from the tailpipe side, they do not work on manifold pipes with e.g. interference outlets

M48x2 e.g. for
