Application: Subaru WRX/STI (GDB/GRB/VAB) Forester XT (SG)
Part Type: Replacement BOV Inlet Gasket – Suits T9003/T9503

GFB is an Australian engineered brand best known for its blow off valves, and this small but important gasket keeps that seal factory tight. It's a direct replacement for the inlet flange on the T9003 and T9503 BOVs, designed to restore a proper seal where the valve meets the turbo inlet pipe on your Subaru WRX or STI. SKU 6705.

This listing covers the WRX and STI (2001-2007), STI (2008-2014), STI (2015-2021), and the Forester XT (2006-2008).

Note: Newer GFB BOVs use an O-ring on the inlet flange instead of a gasket and do not require this part. Confirm your BOV model is the T9003 or T9503 before purchasing.
