1981 Mercedes-Benz 300SD Air Filters

Carquest Premium Air Filters are designed and rigorously tested to ensure contaminants are removed to provide optimal engine function.

Product Features:

• Superior fit that meets requirements for Original Equipment form, fit, and function
• High effciency media delivers premium performance at 98% filtration efficiency
• Reinforced metal screen backing with anti-rust coating
• High performance sealing materials and media pleat stabilization for worry-free performance
• Polyurethane frame provides structural strength
• Media embossing technique allows for superior efficiency and dust capacity

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.
