RSI Lower Injector Spacer Set for 60mm Dodge Viper Fuel Rails

This set of 10 injector spacers is designed to work ideally with Viper Intake manifolds for mid-length injectors.  This will adapt the height of the injectors up to enable the use of aftermarket rails like our RSI Billet Fuel Rail Kits.  The lower injector spacer is needed to prevent the wiring connector from interfering with proper O-ring seal.   These billet aluminum adapters come with the correct O-ring.
