Show original supplier description

The Forge Motorsport Atmospheric and Recirculating Valve is an expertly manufactured and designed performance component, originating from the UK. This valve is specifically engineered for the Hyundai i30N, Kona N, and Veloster N, and directly replaces the OEM part number 282342-CTA4. It offers the flexibility to be used as either a fully atmospheric (blow off) valve or a recirculating valve, allowing users to choose their preferred setup. The valve features an innovative design that uses boost to a side entry, a key advantage over competitors as it prevents the valve from lifting under varying boost pressures. This design also eliminates the need to adjust the internal spring rate when tuning the vehicle, simplifying the process and ensuring consistent performance. The piston is equipped with heat-stabilised Viton O-rings and lubricated with high-temperature Mobil1 grease for enhanced durability and extended service intervals. The valve is fully serviceable and can be rebuilt in minutes, with rebuild kits available separately. It comes with a Forge Lifetime Warranty. This kit includes all necessary parts for both atmospheric and recirculating configurations.
