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

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year Warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please call our customer service team on +49(0)3222/1097-308 or email info@forgemotorsport.eu.
Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.

Expert Answers
Is it okay to drive on rainy days?
Yes there is no problem with water ingress with this product.
Hello, I purschased the item but I was wondering if I need to torque the nuts? I used the factory nuts.
Hello
You need to fit the supplied fasteners not the OE nuts and just make sure its tight.
Dear all, Do you have any idea if this dump valve will fit a regular BC3 i20 N Line? This is the 3 cilinder 1.0 liter version of the car (non-hybrid). Or would it be better to use the dump valve intended for the 1.4 tgdi i30? Thanks in advance.
Hello
We are developing a new product for this engine, It will be avalible later this year, this product is not compatible.
Good morning I have a question I hope you will answer me, I bought the Forge dump valve and I installed it in external discharge, if I put it in internal discharge, there is no risk for the turbo and is it better for the engine? Thank you for your reply.
Hello , there is no risk to the turbo if this is set up the dump atmospherically.
