The cabin air filter functions as a barrier that prevents dust, pollen, smog, and other harmful particles from entering your vehicle’s interior, creating a healthier and more comfortable environment for you. On the other hand, the engine air filter protects the engine from those same contaminants, such as dirt, debris, and even tiny bugs. To ensure smooth engine operation and efficient combustion, it is important to maintain a balance of fuel and air mixture. This can be achieved by allowing only clean air to enter the engine. If you are in need of an oil air filter and want to have one for your vehicle, then D&K Internationals is the best stop for that!
