X1/9 M8 X 57 Manifold Head Stud

M8 X 57mm long replacement for a cylinder head manifold inner stud. Correct factory thread lengths of 13mm and 23mm. 2 inner studs required in total. Sold individually.

Important: Avoid using general purpose studs of the same length that do not have a short thread end as they screw into the head too far and leave insufficient thread for the manifold nut & washer.
