GFB Hybrid Dual Port BOV – Mitsubishi Evo 1-10 / Subaru WRX STI (GC8) – 33mm

Application: Mitsubishi Evo 1-10 / Subaru WRX STI (GC8)
Part Type: Hybrid Dual Port BOV – 33mm

GFB built its reputation on the original dual port blow off valve, and the Hybrid is the modern continuation of that idea. Staged recirc and atmosphere venting means you get the classic blow off sound without the stalling or backfiring issues that plague single port atmo valves on MAF equipped cars, making it a great fit for the Mitsubishi Evo and Subaru WRX.

This listing covers the 33mm Hybrid BOV for Mitsubishi Evo 1-3, Evo 4-6, Evo 7-9, Evo X, Lancer Ralliart, 3000GT/GTO and Colt Ralliart models, along with Subaru Liberty GT BM/BR (2010-2014) and WRX/STI GC8 (97-98).
