GFB Hybrid Dual Port BOV - Mitsubishi Lancer Evo I-X / Subaru WRX/STI (GC8) - 33mm
The GFB Hybrid 33mm is a dual port blow off valve kit for every Mitsubishi Lancer Evolution from Evo I to Evo X, plus the Lancer Ralliart, Colt Ralliart and 3000GT/GTO. It also fits the Subaru Liberty GT (BM/BR, 2010-2014) and the 1997-1998 WRX and STI (GC8). Staged recirculation and atmosphere venting, adjustable for full recirculation, full atmosphere or 50/50, avoids the stalling and backfiring that single port atmosphere valves can cause on MAF-equipped cars. Each supported model gets a direct bolt-on kit, and the classic blow off sound is kept.
