GFB Respons Dual Port Variable BOV Blow Off Valve - Hyundai i30 SR (PD) / Veloster Turbo (JS) / Kona (OS) / Kia Cerato (BD)
GFB pioneered the dual port blow off valve back in 1999, and the Respons takes that concept further with a patented venting bias adjuster. Fit this to your i30 SR, Veloster Turbo, Kona or Cerato and you can dial in anything from full recirculation to full atmosphere venting, giving you the blow off sound you want without the fuelling issues that plague cheaper valves on MAF equipped cars.
This listing covers the Hyundai i30 SR (PD) 2016-2019, Hyundai Veloster Turbo (JS) 2019+, Hyundai Kona (OS) 2017-2020, and Kia Cerato (BD) 2018+, all fitted with the 1.6T-GDI engine. SKU T9011 is a direct bolt-on kit that installs in the factory location with no adaptors required.
Note: Kona OS fitment applies to the G4FJ Gamma engine only — confirm engine code before ordering.
