Atmospheric CTS Turbo BOV kit (blow-off valve) for Audi vehicles with a 2.0T engine and IHI turbocharger. The kit is made from CNC-machined T6061 aluminium and can be fully serviced.
The valve operates with the factory electronics, does not trigger the engine warning light and is installed on a plug-and-play basis, without extending the wiring. It replaces the factory plastic valve, which can suffer from diaphragm damage, cracked plastic or electrical faults.
The piston design ensures a long service life, simple installation, serviceability and a distinctive air-release sound. The valve is slightly shorter than the original, so it also fits well in the tightly designed engine bays of modern VAG vehicles.
Important compatibility information
The kit is suitable only for engines with code CYMC and an IHI turbocharger. It is not compatible with the DMSA and DPAA engines from model year 2020+, which use a Borg Warner turbocharger with part number 06N145702D.
