Mann-Filter – Premium OE Air Filter: OE Quality, Reliability & Fit for European Nameplates (Part No.C 26 168)

Premium OE Air Filter: OE Quality, Reliability & Fit for European Nameplates

from

$12.29
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.

Product Features:
  • Highest degree of dirt separation and high mechanical stability
  • Perfectly adapted in form and function to the widest possible range of installation situations
  • Filter even the smallest particles out of the intake air
  • Enables an optimum composition of the fuel-air ratio and ensures that the engine performance is consistent
  • High dust holding capacity ensures reliability throughout the entire service interval

Poor quality air makes you tired, irritates your eyes and respiratory tract. Cabin air filters from MANN-FILTER ensure improved comfort and fresh air in your car, as they almost completely free the air entering the vehicle of dust, pollen, soot and other pollutants: precisely those substances which are causing health problems for more and more people, especially asthmatics and those with allergies. Like all filters, however, MANN-FILTER cabin air filters also have to be changed regularly. As a general rule, they should be serviced at one-year intervals or after every 15,000 km travelled. Misty windows, a stuffy cabin and a malfunctioning air conditioning system are also sure signs that replacement is necessary. Next time you are changing your cabin air filter, play it safe and choose a patented high-tech filter from MANN-FILTER. Our products are a perfect fit and of verified original equipment quality. Detailed installation instructions mean that assembly is quick and easy
