CTS 1.8T 06A Block Breather -10AN

The CTS Turbo 1.8T 06A Block Breather replaces the restrictive factory PCV valve setup with a precision-machined billet aluminium fitting featuring a -10AN port. Designed specifically for the 06A engine block found in Audi TT 8N, A4 B6 and VW Beetle MK1 models, this breather upgrade provides improved crankcase ventilation under high boost conditions. The -10AN connection allows direct integration with aftermarket catch can systems or custom breather configurations, making it an essential component for tuned 1.8T engines running elevated cylinder pressures. CNC-machined construction ensures reliable sealing and long-term durability in demanding performance applications.
