The Radium Engineering 10AN PCV valve-cover adapter for Evo 8 / 9 converts a PCV outlet to a 10AN male (7/8-14) thread while providing a generous 12.4 mm (1/2") internal diameter for high flow. It can be installed as a weld-in or press-in fitting, offering flexibility for installation into valve covers or custom plumbing where a durable, high-flow PCV feed is required.
