Our Ninja H2 lower fuel rail is a direct replacement for the factory lower fuel rail & it fits perfectly on the factory throttle body & injectors, it is compatible with the OEM plenum or our H2O intecooler kit plenum. Only available as a "Pro Race" version that uses AN-6 fittings for maximum unrestricted fuel flow to the injectors, internal bore of the rail is 10mm which is more than double an OEM rail so there's no chance of injectors starving of fuel even when using E85.
Note: custom fuel lines & our Pro Race upper rail will be required when using this rail as it uses AN-6 style connectors.
Fits to your OEM throttle body using factory hardware.
What's included: 1 x billet lower fuel rail, 1 x 90 deg AN-6 male fitting, 1 x straight AN-6 male fitting & 1 blanking plug. as there are a few possible ways to configure the fuel lines , fittings are supplied loose so you can setup as required.
