Uprated exhaust manifold stud kit for TD5, designed to help eliminate studs breaking off in the cylinder head.
This is often due to manifold warping typically made apparent by a high pitched ‘squeal’ under heavy acceleration.
These studs are made with a higher grade material, are longer and are supplied with expansion spacers and new flange nuts .
The nuts should be tightened to 25nm (18lbf.ft).
We also recommend replacing the manifold to head gasket. Please see our part listing ASE08 or ASE09 for replacement gaskets.
Compliments our free flow performance exhaust manifold – ASE01.
Alternatively we sell the manifold, studs and gaskets as a package – ASE33.
