Description

The CTS Turbo Manual Boost Controller (MBC), part number CTSMBC, is engineered as a direct replacement for the factory N75 valve in many Volkswagen and Audi 1.8T applications. This manual boost controller provides enhanced accuracy in boost control, leading to more stable and predictable psi levels compared to the stock unit. It is particularly beneficial for setups utilizing larger turbochargers and custom tuning, allowing for precise adjustment of boost pressure. This part fits a range of Audi and Volkswagen models equipped with the 1.8T engine, including the Audi A4 B5 (1996-2001), Audi TT Mk1 (1998-2007), Volkswagen Golf/GTI Mk4 (1999.5-2005), and Volkswagen Passat B5 (1998-2005), across various submodels and drive configurations (FWD, Quattro, 4Motion).
