Introduction

ARP 14mm Head Stud Set

IAG’s 14mm Head Stud Set is designed for use on high horsepower Subaru engines. The larger size of the stud increases its load capacity which in turn helps to prevent the cylinder head from lifting and creating head gasket failures. The oversized head studs require drilling and tapping the case as well as enlarging locating dowels to accept the larger studs. In addition the cylinder head will also require the head stud hole clearances enlarged to accept the studs.

*Drilling the head gaskets to clear the larger 14mm head studs is required for fitment.
