Video description
If you're planning a performance engine build for your Subaru, ARP Head Studs (260-4701) should be at the top of your parts list. Designed for 2002–2014 WRX and 2004–2021 STI models, these premium head studs provide the clamping force needed to keep your head gasket sealed under increased boost and cylinder pressure.
