This secondary air injection (SAI) pump is required for the Integrated Engineering Audi Volkswagen 2.0T TSI Cold Air Intake (MK5, MK6 GTI, Jetta, CC & 8P A3), or any other relevant parts, if your engine has a CBFA engine code. Read the note below to for further clarification.
Important Note
The MK5/MK6 2.0T TSI engine has two different engine codes. CBFA engine codes are equipped from the factory with a secondary air injection (SAI) pump that connects to the factory intake box. These engines require a small breather filter for this SAI line when installing an aftermarket intake. CCTA engine codes do not have this SAI pump and will not require this filter. Identify your engine code using the photos below, and add this SAI filter kit above if needed when ordering your intake.
