Keep clean, contaminant-free air flowing to your engine with the Bosch Engine Air Filter 5539WS, a panel-style BOSCH engine air filter designed and tested as a direct OE replacement. Its fit and form are dimensionally validated versus OE for easy installation, and it drops in across a wide range of Audi, BMW and Volkswagen models, including the 1998-2005 Volkswagen Passat 1.8L / 2.0L / 2.8L / 4.0L, 1998-2004 Audi A6 Quattro 2.7L / 2.8L / 3.0L / 4.2L, and 2000-2006 BMW X5 4.4L / 4.6L / 4.8L.

• High-velocity cellulose media: captures wear-inducing contaminants while maintaining low airflow restriction for a steady supply of clean air.
• Optimized pleat design: balances air velocity with high particle-holding capacity for advanced filtration performance.
• Resin-impregnated construction: provides stable pleat geometry and moisture resistance for long-term durability.
• Premium polyurethane seal: a gasket/seal is included and helps prevent unfiltered air from bypassing the filter.

Every filter is air-flow tested, and replacing it on your vehicle's recommended maintenance schedule helps sustain normal engine performance and fuel economy while reducing the risk of costly repairs. It also fits many other Audi and BMW models; see the "Vehicles it fits" section for the full list. Most listed vehicles use one filter, while some use two; the "Vehicles it fits" section shows the quantity for each vehicle. Country of origin: China.
