nope, the coupling went over the stock aluminum piece where the ccv is at. just take out the stock air box and that black tube that runs to it. then you have the aluminum part that has the ccv running up through it. then you put the coupler on there and then the 4" 45* elbow, then the filter and your done. i got the stainless for free so i like it better over using pvc and stuff like some people use. the pvc will work though, i have used it on 2 other guys trucks in the past.
