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

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

GFB has been refining dual port blow off valves since 1999, and the Respons is their smartest version yet. Using a patented venting bias adjustment system, it lets you dial in exactly how much air vents to atmosphere versus recirculates, giving you the sound you want without the stalling or fuelling issues that plague poorly designed valves. It's a great fit for the Subaru WRX, Forester XT and Levorg platforms.

This listing covers the Subaru WRX VA (2015-2021), Forester XT SJ (2013-2018) and Levorg VMG (2014-2021). SKU T9007. GFB offers direct bolt-on kits for these platforms, fitting straight into the factory location with no adaptors or modifications required.
