A car consists of several filters that work in harmony to keep the internal systems clean, most notably the oil filter, air filter, fuel filter, and cabin filter. The oil filter plays a vital role in protecting the engine from impurities resulting from friction, while the air filter prevents dust from entering the air passages and combustion system. The fuel filter ensures that clean fuel reaches the injectors, which maintains combustion efficiency and reduces fuel consumption.
Neglecting to change filters leads to engine strain and decreased efficiency, and may cause costly malfunctions. Therefore, it’s always recommended to adhere to the replacement schedules specified in the car manual or according to technicians’ recommendations, as a simple and low-cost replacement can protect the car from major breakdowns later.
