Genuine Audi Filter Element Air Filter 4E0129620C OEM A8 S8 - Audi (4E0-129-620-C)

Genuine Audi Filter Element is the genuine OEM air filtration component designed specifically for the Audi A8 and S8 equipped with the 4.2L engine, covering model years 2004 through 2010. This Audi A8 S8 OEM Filter Element ensures that only clean, precisely metered air reaches your engine's intake system, protecting sensitive fuel injection components and maintaining the exact air-to-fuel ratio your engine was engineered to deliver. Unlike aftermarket alternatives, the genuine 4E0129620C is manufactured to Audi's exacting specifications, using filtration media density and frame geometry that matches the original airbox dimensions perfectly. Aftermarket air filters frequently compromise on material quality or fit tolerances, which can allow unfiltered air bypass or restrict airflow — both of which directly impact engine performance, fuel economy, and long-term reliability. For a high-performance engine like the 4.2L V8 found in the A8 and S8, maintaining factory-level filtration integrity is especially critical to preserving horsepower output and protecting internal components from premature wear. Whether you're searching for an Audi A8 air filter, S8 airfilter replacement, or the specific part number 4E0-129-620-C, choosing genuine OEM guarantees a direct, no-modification fit every time. Audi Henderson is an authorized Audi dealer, and every genuine OEM part sold comes backed by the manufacturer's warranty for complete peace of mind.
