GFB Replacement BOV Inlet Gasket - Subaru WRX (GH/GE) Forester XT (SH) Liberty GT (BL/BP) / Nissan Skyline (R32/R33/R34) Stagea (WC34) / Mazda 3 MPS (BK/BL) 6 MPS (GG)
GFB builds some of the most trusted blow off valves on the market, and this small but essential part keeps your T9001, T9002, T9501, T9502 or T9006 BOV sealed properly against the inlet flange. A worn or missing gasket is a common cause of boost leaks, so having a genuine replacement on hand is cheap insurance for your turbo setup.
This listing covers the inlet gasket for GFB BOVs fitted to the Subaru WRX (GH/GE), Forester XT (SH) and Liberty GT (BL/BP), as well as the Nissan Skyline (R32/R33/R34) and Stagea (WC34), plus the Mazda 3 MPS (BK/BL) and 6 MPS (GG). SKU 6704.
Note: newer GFB BOVs use an O-ring on the inlet flange instead of a gasket, so this part is not required for those units. Check your BOV model before ordering.
