Hyundai i20N & NLine Forge Motorsports Blow Off Valve

Hyundai i20N & NLine Forge Motorsports Blow Off Valve


Forge Motorsports Blow Off Valve Diverter for the i20N & N-Line SmartStream 1.6L models.


Our uprated valve for the Hyundai i20N and the i30/Elantra N Line has been expertly manufactured and designed in the UK, meaning we can provide the industry leading valve for your vehicle. Specifically designed for the Hyundai, this valve can be used either as a fully atmospheric (blow off) valve, or a recirculating valve - you choose!


Our unrivalled design uses a boost to side entry on the valve meaning unlike our competitors the valve cannot lift under high or low boost applications. The advantage of this eliminates the need to change the valves internal spring rate to a higher tension when tuning the vehicle. This valve is finished in anodised black or anodised red to not only give this product the wow factor out of the box, but also to improve the aesthetics of the engine bay of your vehicle.


Note: Forge Blow Off Valve is only either Vent to Atmosphere or recirculate only. Not both. Only the GFB is dual vent and recirculate.
