Get rid of those dusts chocking our air filter, our engine need also an adequate filtered air. The reason probably, I have an inefficient engine is it cannot get proper air volume because of particles blocking the air filter, it might be not be a major part of engine but it's one of the most important. Consider yourself like that as a person, and you must be clean all the time, you are a very important part of our home called earth. Good afternoon Noisers.
