2011 BMW X3 Air Filters

Carquest Premium engine air filters are designed to meet OE fit, form and function for optimal filtration and engine protection. High-quality paper, enhanced bonding, and reinforced metal screen backing give Carquest Premium air filters the added strength and durability that modern engines demand. Built to meet or exceed original equipment standards, Carquest Premium air filters provide exceptional engine protection and optimal performance in all driving conditions.

To achieve optimum performance, combustion engines require clean intake air. If pollutants in the air, such as soot or dust, get into the combustion chamber, pitting may occur on the cylinder heads, causing premature wear of the engine. The function of electronic parts located between the suction and the combustion chamber may also be significantly impaired. MANN-FILTER air filters are the end of the road for all dirt particles. No matter whether it’s dust, pollen, sand, soot or even water droplets – thanks to the highest degree of dirt separation and high mechanical stability, MANN-FILTER air filters filter even the smallest particles out of the intake air. This enables an optimum composition of the fuel-air ratio and ensures that the engine performance is consistent. In order to guarantee performance, air filters must be checked regularly, as a blocked filter will impede the air supply to the engine. The possible consequence of this is: the fuel may not be completely burned and may in part be discarded without being used.
