Forge Motorsport were the OG’s of this original groundbreaking design, and we still lead the marketplace with customer service and after care with this innovative blow off valve - Often copied never bettered

This is our piston version of our very popular solenoid driven valve for the 2013-on VAG 1.8 TSI/TFSI engine (US codes CPKA and CPRA) and 2.0 TSI/TFSI engine (Euro code CNTA, CHHA, CHHB, CHHC, CZPA, CJXB and CJXC;US codes CPLA and CPPA)  including Golf MK7 R. This valve is a full replacement atmospheric blow-off valve (i.e. noisy) that integrates seamlessly with the OEM electronics and results in no detriment in performance, and absolutely NO fault codes or check engine lights, which isn’t something that can be said of our competition!

Not only do you get the famous Forge blow off valve sound but this valve also increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it could cause premature failure, especially on tuned engines and modified vehicles.

Like our full replacement recirculating valve option, this valve is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which results in a boost leak. The later revision OEM valves have a longer lift but ultimately the plastic brittles and in extreme circumstances, parts of the plastic can break off. Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning-fast
