CTS Turbo MK7 Billet SAI breather adapter

The CTS Turbo MK7 Billet SAI breather adapter is a precision-engineered solution for VW GTI MK7, 7.5 and MK8 models. CNC-machined from billet aluminium, this adapter replaces the factory secondary air injection port when the SAI system is removed or bypassed. It provides a clean, reliable breather connection point for crankcase ventilation setups, eliminating the unused SAI port while maintaining proper PCV system function. The durable anodised finish resists corrosion, and the direct bolt-in design ensures straightforward fitment to the cylinder head without modifications.
