Each rail carries three 8AN ORB threaded ports, six across the pair, opening the door to proper AN plumbing, a regulator, a gauge, or a pulse damper. Machined thermal insulating spacers are included for injector height flexibility and heat isolation, and the rails suit all fuel types including E85.\u003c\/p\u003e\n\u003ch3\u003eChoose Your Version\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase-I EZ30 (20-0764-02)\u003c\/strong\u003e: for the original EZ30, identified by a single exhaust port per bank and Subaru's air-assist injection.

Injector Dynamics 1050.34.14.14, 1300.34.14.14, 1700.34.14.14, and 2600.34.14.14 are examples that fit.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ePhase-I EZ30\u003c\/strong\u003e has 11mm injector bores and takes the factory air-assist injectors with no modification. Those OEM injectors are not replicated in the aftermarket, so going aftermarket means installing the supplied Radium injector seats and using a 48mm injector with an 11mm upper and 14mm lower O-ring, such as Injector Dynamics 1050.48.11.14 and its siblings.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ePhase-II EZ30 and EZ36\u003c\/strong\u003e rail is an upgrade rail, not a conversion: OEM or OEM-equivalent injectors are required, matching factory height and O-ring dimensions.
