Fits select 2002-2012 Subaru Impreza WRX, WRX STI, Legacy GT, Forester XT, Baja Turbo, and Saab 9-2X Aero (EJ20 / EJ25).Ensure a reliable head gasket seal on your EJ-series engine with the ARP 260-4701 Head Stud Kit. Factory head bolts can stretch under the high cylinder pressures found in turbocharged applications, potentially leading to gasket failure. These ARP head studs provide significantly higher clamping force and more consistent torque loading than OE hardware, making them an essential upgrade for high-boost builds or routine head gasket replacements.
