Aston Martin intake manifold Vantage 4.7 V8 9G33-9424-AA
The 9G33-9424-AA is the genuine OEM intake manifold assembly specifically designed for the Aston Martin V8 Vantage 4.7L (primarily for the AM11 and AM15 engine variants used from roughly 2008 through 2018).
Because Aston Martin shared significant engineering and parts sourcing with Ford during this era, the part number follows the standard Ford-style alphanumeric coding (the “9G33” prefix typically denotes the 4.7L engine cycle, whereas “6G33” was common for the earlier 4.3L models).
Key Specifications & Details
-
Application: Aston Martin V8 Vantage (4.7L V8 models).
-
Material: High-grade composite/plastic (designed to reduce weight and heat soak compared to traditional aluminum).
-
Role: Directs the air-fuel mixture into the cylinders. It houses the mounting points for the throttle body and various vacuum sensors.
-
Cross-Compatibility: While some 4.3L manifolds (e.g., 6G33-9424-AD) look similar, the 4.7L manifold is tuned for the increased displacement and airflow requirements of the larger engine.
Common Issues to Watch For
If you are looking for this part due to a performance issue, these are the typical “failure” points for this specific manifold:
-
Vacuum Leaks: Over time, the composite material or the gaskets can develop small cracks or perish, leading to a rough idle or “Lean” error codes ($P0171/P0174$).
-
Oil Contamination: If the AOS (Air-Oil Separator) fails, oil can pool inside the plenum of the manifold, occasionally gumming up the throttle body or sensors.
-
Gasket Compression: The gaskets ($6G33-9P851-AB-PK$) are often the culprit rather than the manifold itself. It is standard practice to replace these whenever the manifold is pulled.
