GFB Hybrid Dual Port BOV – Subaru WRX (VA) / Forester XT (SJ) / Levorg (VM)

Application: Subaru WRX (VA) / Forester XT (SJ) / Levorg (VM)
Part Type: Hybrid Dual Port BOV

GFB pioneered the dual port blow off valve back in 1998, and the Hybrid is the valve that started it all. Its staged venting design opens the recirculation port before the atmospheric port, giving you that signature blow off sound without the stalling or MAF-related hesitation that plague atmo-only valves. It's now fully adjustable between full recirc, full atmosphere, or a 50/50 blend, so you can dial in the exact response you want for your WRX, Forester XT, or Levorg.

This listing covers the Subaru WRX (VA), Forester XT (SJ), and Levorg (VM), using GFB's direct bolt-on fitment kit for each specific chassis.
