Question

DentroTest · Accepted Answer

The air filter retains dust particles and impurities from the outside air before they enter the engine cylinders. Over time and with the kilometers driven, the filter element becomes saturated, which hinders the passage of clean air, worsens combustion, increases fuel consumption and accelerates internal engine wear. That is why it must be replaced periodically, following the maintenance plan and the manufacturer's recommendations, as well as the vehicle's operating conditions. Conventional air filters are not self-cleaning: they accumulate residue until the end of their service life, so they cannot go without being replaced. Nor is it the season of the year that decides when to change it: what determines it is the manufacturer's interval and the condition of the filter, not that it gets dirtier in winter or in summer.
