Review on 🚀 High-performance Torque Solution Blow Off Valve Adapter for VW Golf, GTI, MK7 2015+ and Audi A3, S3 - Fits Jetta, Passat, Beetle too! by Kevin Parker

Good for 2018 MK7.5 GTI. You just have to be very careful when installing it. When I removed the stock bypass valve. It came loose and the tension spring fell off and was lost in the engine compartment. I had to buy a new valve. Which cost me $160! The $50 mod went over $200 very quickly. It was my stupid mistake, so nothing from Torque Solution. HOWEVER -1 star because the rubber o-ring on the TS valve adapter detaches and falls back into the engine bay on its own. I used the thicker o-ring from my new OEM diverter valve, which fits the TS adapter with little effort. Again, if you don't want to make the $160+ mistake, be very careful.
