Rather than leaving your fuel pressure regulator referencing a single cylinder runner — which can introduce unwanted pressure pulsations — this kit moves the reference point to a plenum-based source, giving the FPR a more stable and representative signal. It's the same approach used on the earlier \u003cstrong\u003e2001–2007 STI\u003c\/strong\u003e platform, and it makes a genuine difference in fuel delivery consistency on modified builds.\u003c\/p\u003e\n\n\u003cp\u003eThis listing covers the \u003cstrong\u003eSubaru STI\u003c\/strong\u003e across the \u003cstrong\u003eGRB\u003c\/strong\u003e (2008–2014) and \u003cstrong\u003eVAB\u003c\/strong\u003e (2015–2021) chassis platforms.\u003c\/p\u003e\n\n\u003ch3\u003eKit Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePlenum-based vacuum reference fitting (COBB) — replaces OEM individual cylinder runner reference\u003c\/li\u003e\n  \u003cli\u003eReducing \"T\" fitting\u003c\/li\u003e\n  \u003cli\u003e4mm silicone vacuum line\u003c\/li\u003e\n  \u003cli\u003e6mm silicone vacuum line\u003c\/li\u003e\n  \u003cli\u003eBlack zip ties\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eVehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above.
