Mercedes AMG A45 Blow Off Valve Atmospheric BOV, Black is a purpose-built upgrade for the 2.0 turbocharged M133 engine found in the AMG A45, with compatibility for PRE facelift A45, CLA45, and GLA45 models. This BOV is 100% new, constructed from aluminum and finished in an anodized black, and it delivers true vent-to-atmosphere operation with the distinctive TSCHH sound on lift-off. The kit is a direct OEM bolt-on fit and includes a complete fitting kit with vacuum hose tee-piece for straightforward, professional installation.

In standard factory tune, the turbo’s blow-off port is blanked off. When you remap, or take the car to the track, driveability can be affected under hard acceleration—potentially dropping engine and turbo performance and reducing turbo life. This atmospheric BOV opens the port to vent to atmosphere, helping maintain consistent boost control and delivering the classic audible venting sound that enthusiasts value. It’s designed for PRE facelift A45/CLA45/GLA45 AMG 2.0 turbocharged M133 vehicles and is built to withstand demanding use while remaining serviceable for maintenance or upgrades.

All items are to be fitted by a professional and no installation instructions are included for this reason. Please allow slight measurement variation due to manual manufacturing tolerances. This product ships from Mainland China and comes with a full fitting kit to ensure a secure, OEM-style installation.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
