4H0129616J Engine Air Intake Hose for Audi A8 D4 4.0T 2010-2017

Engine Air Intake Hose for Audi A8 D4 4.0T (2010–2017) (4H0129616J)

1. Part Number: This engine air intake hose is identified by OEM part number 4H0129616J, ensuring strict compliance with Audi’s engineering standards. The code validates authenticity and guarantees a factory-precise fit for seamless integration into the air intake system.
2. Vehicle & Engine Fitment: Specifically engineered for the Audi A8 D4 (2010–2017) equipped with the 4.0T V8 twin-turbo engine. Verify your vehicle’s production year and engine code (e.g., CEUA, CEUB) to confirm exact compatibility with the 4.0L forced-induction powertrain.
3. Function & Quality: Channels filtered air from the air box to the turbocharger, critical for maintaining optimal air flow and combustion efficiency. Constructed from heat-resistant EPDM rubber with reinforced textile layers, it withstands underhood temperatures (up to 120°C) and turbocharged pressure fluctuations. Precision-molded bends and secure clamp fittings ensure airtight performance, preventing unfiltered air ingress. Replacing cracked or worn hoses restores proper airflow, protects the engine from debris, and preserves the 4.0T’s power output in Audi A8 D4 models.
