Adapter plate for the crankcase ventilation, suitable for all 2.0L TSI of the first and second generation, such as in the Golf 6 GTI. Ideal for the installation of a catchtank system for an external crankcase ventilation and Dash 10 lines. This prevents creeping loss of boost pressure via the susceptible standard crankcase ventilation valve on TSI engines. Leaky PCV valves cause the boost pressure to escape into the crankcase, which not only reduces engine performance, but also creates excessive overpressure in the crankshaft drive. This can cause further leaks in the engine. Furthermore, it can lead to an out-of-round idle. The advantages are obvious: CNC made of high quality aluminium Billet version without welds No problems due to too high pressure Constant boost pressure Fits Plug and Play incl. screws No more leaks No coking of the intake valves Especially recommended for tuned engines For 2.0L TSI EA888 engines with chain drive Our complete Catchtank Kit with TÜV you can find here Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
