A super durable and responsive aluminium piston. Fully serviceable and rebuildable in minutes. Available in anodised Black OR Red. Unlike other valves on the market, ours produces no check engine lights (EML).Our uprated valve for the Hyundai i20N and the 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. We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner. This fits the following vehicles: [car_parts_fittings].
