IAG ARP 14mm Head Stud Set, 2004-2021 STi & 2006-2014 WRX

IAG's / ARP 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 splitting the 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.

Included:
• (x12) ARP2000 14mm x 1.5mm Head Studs
• (x12) ARP Washers
• (x12) ARP Nuts
• (x1) ARP Fastener Assembly Lube
