Radium Engineering Fuel Rail for Honda F/H Series Engine - 20-0870
This fuel rail has been confirmed to work with the following Honda engines: H22A1, H22A4, H23A1, F20A, F20B, F22A1, F22A4, F22A6
However, there are likely many other variations that are compatible. And even though the Radium Engineering fuel rail has 3 fuel rail mounts, it will work on many of the 2-bolt intake manifolds, as shown below.
Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from 6061 aluminum, anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors, or any equivalent aftermarket injector, can be used.
The fuel rail is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM spacers are required for mounting the fuel rail.
FUEL INJECTOR COMPATIBILITY
This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
