Exhaust Repair Stud
M11 x 1.25 reducing to M10 x 1.25
These very handy exhaust manifold studs are oversize by 1mm (M11x1.25) allowing you to re tap the cylinder head to M11 to repair damaged threads.
The stud reduces to M10 so manifolds will fit straight back on.
Fensport Tip: We find them to be a far more effective repair than helicoiling.
Note: Can be used anywhere in place of M10 studs.
