Porsche Cayenne, Panamera,958, Turbo, GTS, V8, 94811001675

For the Porsche Cayenne (958) and Panamera (970) with the 4.8L V8 engine (Turbo, Turbo S, and GTS), the part number 94811001675 (or 948-110-016-75) identifies the Intake Air Distributor (Intake Manifold).

While many searches for “948” parts on these V8s lead to the high-pressure fuel pump (HPFP), this specific number refers to the large composite manifold assembly that sits atop the engine.

1. Technical Specifications & Role

The intake manifold on the 4.8L DFI (Direct Fuel Injection) engine is a complex component designed to optimize airflow for both naturally aspirated (GTS) and forced induction (Turbo) applications.

• Material: High-strength composite/plastic.

• Compatibility: * Cayenne (958.1 & 958.2): S, GTS, Turbo, and Turbo S models (2011–2018).

  • Panamera (970.1 & 970.2): S, 4S, GTS, Turbo, and Turbo S models (2010–2016).

• Supersessions: You may also see this part associated with numbers 94811001671 or 94811001676 as Porsche updated the gaskets or internal flapper designs.

2. Common Reasons for Replacement

While not a “wear item” like a spark plug, this manifold is often replaced due to:

• Plastic Degradation: Over time, the heat cycles of the V8 engine can make the plastic brittle, leading to cracks and vacuum leaks.

• Oil Contamination: In 2026, many of these engines are reaching higher mileages where the AOS (Air Oil Separator) allows oil mist into the manifold, potentially gunking up the internal resonance flaps.

• Warpage: If the engine has suffered a significant overheating event, the mounting flange can warp, preventing a proper seal even with new gaskets.
