This GReddy Type R replacement diaphragm is a service part intended for the GReddy Type R blow-off valve. As a direct replacement component, it restores the valve's sealing and actuation surfaces and is used when servicing or rebuilding the Type R BOV. It provides a dealer- or shop-service option to maintain correct BOV operation without replacing the entire assembly.
