GFB Deceptor Pro II Electronic Blow Off Valve - Subaru WRX/STI (GC8) MY99-00 / Forester GT (SF) / Forester XT (SG) MY03-05 / Liberty B4 (BE/BH)
GFB has been refining blow off valve technology for decades, and the Deceptor Pro II takes their Respons concept further by putting sound control right in the driver's hands. Fitted to your Subaru WRX, STI, Forester or Liberty B4, it lets you dial in venting bias electronically from a compact in-cabin controller, so you can run silent, full atmospheric blow off, or anywhere in between without touching a spanner.
This listing covers the Subaru WRX/STI (GC8) MY99-00, Forester GT (SF), Forester XT (SG) MY03-05, and Liberty B4 (BE/BH). It's a direct bolt on unit designed to fit into the factory BOV location on these models without cutting or fabrication.
Important: The Forester XT (SG) MY03-05 is only compatible with the Diamond flange BOV. If your vehicle uses the Triangle flange, you'll need GFB part T9503 instead. Check your factory flange before ordering.
