The Injector Dynamics 1750-XDS 1750cc injector set for 2004–2006 Subaru STI applications is configured for a top-feed conversion and is supplied as a matched set of four. These injectors provide the larger flow required for upgraded or high-output builds using a top-feed arrangement, and they install where length and feed orientation match the converted intake and fuel rail setup.
