IAG Performance ARP 1/2" Head Stud Set for Subaru EJ25, FA20, and FA20 DIT

This is the stronger clamping option for builds where you are trying to keep the head gasket situation under control as cylinder pressure goes up.

• Hardware: ARP 1/2" head stud set
• Best fit: Good match for higher-power EJ and FA builds where better clamping is part of the plan
• Build style: Not a dress-up part. This is a real supporting piece for serious engine work

Fitment: Subaru EJ25, FA20, and FA20 DIT applications

Why you'd choose it: Choose this when the engine combo is serious enough that head clamping should not be treated like an afterthought.
