GFB Hybrid Dual Port BOV – Hyundai i20N (BC3) / i30 N-Line (PD) / Kona N-Line (OS) / Sonata N-Line (DN8)

Application: Hyundai i20N (BC3) / i30 N-Line (PD) / Kona N-Line (OS) / Sonata N-Line (DN8)
Part Type: Hybrid Dual Port BOV

GFB built its reputation on the original dual port blow off valve, and the Hybrid brings that world first design back with modern tuneability. Staged recirc and atmo venting cuts stalling risk on MAF equipped cars while still delivering that classic blow off sound under load, and it's now fully adjustable to suit your setup.

This listing covers the GFB Hybrid for the Hyundai i20N, i30 N-Line, Kona N-Line (2021+, Smartstream 1.6T-GDI models) and Sonata N-Line (2021+, 2.5 T-GDI). Each application uses a direct bolt-on kit designed for its specific engine bay.

Important: The i20N, i30 N-Line and Kona N-Line fitments are only compatible with the Smartstream 1.6T-GDI engine (G4FP). This valve does not fit the earlier Gamma 1.6T-GDI (G4FJ) engine, so confirm your engine code before ordering.
