Genuine Bentley V8 Air Filter Set (3W0129320 & 3W0129319)
Description
Unrestricted Performance for the 4.0L Twin-Turbo V8 Engine Maintain the induction integrity of your Bentley with this Genuine OEM Air Filter Set (Bank 1 & Bank 2). These high-density pleated filters are the primary line of defense for your 4.0L twin-turbocharged V8 engine, specifically engineered to provide maximum airflow while trapping microscopic particulates that can damage turbocharger compressor wheels.
Technical Fitment & Compatibility:
- Included Parts: 3W0129320 (Right Hand / Bank 1) and 3W0129319 (Left Hand / Bank 2).
- Application: Bentley Continental GT, GTC, and Flying Spur models (2012–2025) equipped with the 4.0L V8 Engine.
- Engine Protection: Optimized for the 500hp+ variants, ensuring stable air-fuel ratios and preventing "Lean Run" conditions.
Why OEM Matters for Bentley Induction:
- Zero-Leak Seal: Factory-spec polyurethane gaskets provide an airtight seal within the airbox, preventing "dirty air" from bypassing the filter—a common issue with cheaper aftermarket alternatives.
- MAF Sensor Safety: These filters are non-oiled, ensuring no residue accumulates on the delicate Mass Air Flow (MAF) sensors, which can cause erratic idling and check engine lights.
- Precision Pleating: Designed to manage the high-velocity suction of the twin-turbo system without collapsing under boost pressure.
Technical Integration Tip When performing a 20,000-mile induction service, we recommend cleaning the interior of the airbox with a specialized vacuum before installing the new 3W0129320 filters. For the 4.0L V8 platform, ensure the airbox clips are fully seated; an improperly secured housing can lead to air turbulence that disrupts the engine's "Fuel Trim" calibrations.
