Subaru WRX & STi (EJ20 and EJ25) Head Studs

CUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260,000-280,000 psi.
