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 airfilter, older larger valves and sandwich plates will not fit this engine.

Just fitted this to my 2016 polo gti 1.8 tsi. Had to remove the air filter hose as shown in the picture but apart from that.. put 1 and 2 together and it was straight forward. If in doubt get a local garage to install it. Small psst at low rpm and a massive PSSSST under full throttle. WILL turn heads.

Im over the moon with my new BOV kit, so much louder than i expected, but quiet when i want with minimal revs. Im bit of a noob when it comes to cars but this was a super easy installation, around 10 steps which took me about 20 mins. Also loving the sweet spot around 3000rpms, if i come off the gas just right i get a stututu (diverter valve sound) before the ppssshhh, it turns so many heads, if you dont like attention, making people jump and making people smile then i wouldn't advise getting a forge bov kit. Thank you Forge, i'll be back =D

Great product! The noise is amazing. Quiet sounds when at minimal revs but really loud when under acceleration. Had it dyno'd when fitted and unlike other BOVs, there was no loss in power or drop off in torque at all. Didn't fit it myself, but was told it was really easy to do. Would strongly recommend.

Brilliant bit of kit, supplied with easy to read instructions making it fairly easy to fit.

Would definitely recommend the noisy blow off valve!

Thanks forge

GREAT PRODUCT! I purchased this mainly for the sound and the durability over the stock diverter valve. I'm completely satisfied with the performance and easy installation. Anyone that can change oil, can install this piece with the instructions that are included. They include pictures and clear step-by-step procedures. Highly recommend to any fellow VW owners.
