This version has the damper port machined into the underside center of each rail. Stainless steel brackets attach to the factory fuel rail mounting points, so it's a direct swap.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eTwo sets of machined phenolic spacers are included for injector height flexibility and thermal insulation — that's what keeps heat from the head out of the fuel and gives you room to run injectors that aren't exactly OEM length.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCompatible with all fuel types including E85.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 02-14 Impreza WRX (USDM), 07-14 WRX (JDM\/EDM), 07-21 WRX STI, 06-13 Forester XT, 01-03 Legacy GT (JDM), 07-12 Legacy GT, 07-12 Outback XT, 05-06 Saab 9-2X Aero. \u003cstrong\u003eFactory top-feed engines only.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eInjector requirement:\u003c\/strong\u003e all injectors must use 11mm diameter upper O-rings, same as OEM Subaru.
