Exactly as described and works as such. Could swear the engine noise was audibly different.

I have owned my 2004 Single cab 6 cylinder silverado 1500 since day one. I have used competitor brand filters for the entire time. I decided, well let me give this K&N filter a shot. WOW. My truck that I know so well is now very responsive, absolutely no shortage on pull when I give it gas. I have yet to see if I have improvement in my mpg. Needless to say, this is highly recommended. 5 min install and your good.
