i opened up my air filter box because

there was a plastic plate that sat against the filter and only had a 2.5" hole in it!!!! Before the delete, i would change the filter only to find a very dark spot on it about 2.5" in diameter, the rest of the filter was clean!!!!! and this filter is like 10x12!!!! lower tone now....maybe it would sound okay then???
