2026 Audi A3 Quattro Filters and PCVs

The average American spends almost 300 hours in their car every year. That¿s a lot of time spent breathing potentially dirty, unpleasant air. PurolatorBOSS® Premium Cabin Air Filters with Febreze Freshness are designed with triple-layer protection. This powerful combination blocks and controls odors while preventing mold and bacteria growth on the filter. This advanced performance filtration technology also filters out virus aerosols, a vital defense mechanism in today’s environment. The filter effectively captures fine dust particles and inert allergens that have been known to cause respiratory issues. The advanced filtration solution combines the odor eliminating technology of Febreze with an antimicrobial layer that prevents mold, mildew and bacteria growth on the filter. Our highly efficient particulate layer blocks up to 99% of fine particles like road dirt, brake dust, soot, pollen and other iner allergens from entering the vehicle’s cabin – all while optimizing air flow through the HVAC system.

More and more performance, less and less consumption – in order to meet the high demands placed on modern engines, automobile manufacturers demand the absolute highest levels of performance from the engine components used. The oil circuit is of central importance here, as only clean engine oil can permanently ensure consistent engine performance.

If you want to play it safe when choosing an oil filter, choose MANN-FILTER. They are designed for modern high-performance oils and can stand up to even the most demanding technical challenges. As the application areas of oil filters and the demands placed on them vary, MANN-FILTER oil filters are available in different designs.
