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 response. It has also been proven in cars running over 600bhp!
This valve has a very short overall installed height, which enables fitment of this atmospheric valve into the tight space between the turbo and the inlet hose from the air-filter, older larger valves and sandwich plates will not fit this engine.

Compatible Vehicles
Note that the models listed here have either had the part fitted by us or a customer or they are listed as being compatible on industry parts databases. Where it has not been directly fitted by Forge there will then be a separate May Also Fit tab where the make and model will also appear and which details our no-risk approach to purchasing this product, so it is worth checking there as well.
The majority of Forge Motorsport products come with a limited lifetime 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.
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.
