GFB Hybrid Dual Port BOV - Subaru WRX/STI (GC8) / Forester XT (SG)
Application: Subaru WRX/STI (GC8) / Forester XT (SG)
Part Type: Hybrid Dual Port BOV
GFB built its reputation on the original dual port blow off valve, and the Hybrid is the model that started it all. Designed for the Subaru WRX and STI, this valve stages its recirculation and atmosphere vents so the recirc port opens first, cutting stalling and backfire risk on MAF equipped cars while still delivering that classic blow off sound under harder driving.
This listing covers the 1999-2000 WRX, 1999-2000 STI, 1997-2002 Forester GT, 2003-2005 Forester XT, and 1998-2003 Liberty B4 (BE/BH). The valve can be configured for full recirc, full atmosphere, or a 50/50 split to suit your tune and preference.
Important: the 2003-2005 Forester XT fitment is only compatible with the Diamond flange BOV outlet. If your Forester XT has a Triangle flange, you'll need part T9503 instead.
