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. 

This kit only includes the fuel rail and the mounting hardware, making it ideal for custom applications. Extra fittings, hoses and other fuel plumbing items will be needed to complete the installation.

COMPATIBILITY

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.
