Product details
Sized M6 x 35, this Original BMW stud bolt is a cylinder head part for the S14 engine in the 1988–1991 BMW M3 (E30). BMW classes it as a cylinder head part and calls it simply a stud bolt, while it is commonly sold as an exhaust port stud. Each one weighs 4 grams (0.14 oz), and BMW has produced this number since July 1988.

M6 x 35 is the size to match against the stud you are replacing, and it is the figure BMW uses alongside part number 11-12-1-312-096 to identify this piece. The stud sits in BMW's cylinder head group, which also covers the head itself, its gaskets, and the valves.
