O-RING SET, FUEL INJECTOR, SMALL, SET OF SIX, FITS 1980-1987 XJ6 AND 1976-1993 V12 XJS MODELS. (V12s take two sets). The small o-rings are the important ones to change out. They seal the injector to the intake manifold and when they get old they leak air and mess up your fuel injection metering. (EAC2415)
