Injector Dynamics uses it for the 48 mm injector with the spacer arrangement its Nissan and Infiniti applications need, and lists three vehicles against it: the Nissan GT-R R35, the Nissan 370Z and the Infiniti G37. The importer data describes the same thing as a low spacer.\u003c\/p\u003e\u003cp\u003eThere is a trap in the GT-R listing that is worth knowing about before ordering.
