I look at it this way. The OP tried the intake...maybe for performance or maybe for under the hood looks. Bottom line didn't care for the extra noise of our fine Texas dust n pollen filled air being sucked in thru the filters or the added whistle of the turbo. So he added the sucker cover to reduce the noise. May have lost a little performance gains in the process, but if the occasion ever calls for more needed power and boost it is still there with the quick removal of the cover. Sometimes quite is nice.....REAL NICE.
And I have sat in Austin, TX traffic......sometimes you ain't going no where fast!!!!! Of course at other times it seems that you can't go fast enough to get out of the way!!!!
