engine code: AAZ

Without EGR

The Volkswagen Mk3 1.9TD AAZ Intake Manifold (OEM Part Numbers 028129713E for the lower base and 028129837F / 028129637F for the upper assembly or corresponding castings) is a factory-direct replacement part engineered specifically for the 1.9-litre Indirect Injection (IDI) Turbo Diesel engine. This specific engine variant was prominently featured in Canadian-market and European-market Volkswagen Golfs, Jettas, and Transporters during the 1990s.

Direct Fit & OEM Compatibility: This genuine Volkswagen cast component ensures an airtight seal against the cylinder head to properly direct airflow to the combustion chambers.

Design Features: It is distinctively configured with an upward-facing snorkel neck or elbow. This specific layout is highly sought after by enthusiasts for custom intercooler routing or upgrading Vanagon/Quantum JX engine conversions.

If you are replacing a damaged or cracked factory assembly, ensure you pair the installation with a brand-new manifold gasket and high-temperature gasket sealant to guarantee a completely secure, leak-free boost connection.
