Subaru cold air intake filter works just like the ordinary air filter or cabin air filter. The only difference with these three filters is the area where they are installed. The cabin air filter traps off dirt from the air that goes inside the driver and passenger compartment. Whereas, the air filter and the cold air intake filter work both with the engine system, with the air intake system in particular. The latter two air filters, though working for the engine are different from each other because of the type of air intake system with which they are installed. The cold air intake system takes in cold, dense air, and ensure that this air don't become warm when it reaches the engine. Ordinary ones, on the other hand, don't have that special feature of keeping the air as cold as possible. The goal of cold air intake is to improve the combustion process of the engine by letting it breathe more oxygen. When matched with high-flow Subaru cold air intake filter, this air intake system ensures that the engine takes in only clean and dense air which it actually deserves. As the system provides the more oxygen for more complete fuel combustion, the filter makes sure that no contamination could mess up with engine system's operation. Small dirt or few dusts can actually post danger to the engine. But when this air filter get clogged, the service of the cold air intake will become less beneficial. Why? Because lesser air would be able to reach the combustion chambers, affecting then the air and fuel ratio necessary to produce great power. Through simply cleaning this Subaru cold air intake filter, the operation will be restored. But when the filter gets badly damaged, only replacement could solve the problem.
