CTS Turbo Audi B8.5 A4/A5 Catch Can Kit (Flex-Fuel with Aluminum Intake Manifold)

The CTS Turbo catch can kit addresses oil vapour contamination in B8.5 Audi A4 and A5 models fitted with flex-fuel systems and aluminium intake manifolds. Direct injection engines recirculate crankcase vapours that carry oil mist back into the intake, coating valves and reducing efficiency over time. This purpose-built system intercepts contaminants before they enter the manifold, maintaining clean intake paths and protecting valve surfaces. The kit integrates seamlessly with factory plumbing on 2013-2017 B8.5 chassis vehicles, offering straightforward installation for workshop environments requiring reliable solutions for high-performance applications.
