This kit came from necessity.  We have all had or heard of issues with the small return port breaking on our intake tubes.  There is no replacement and a new tube for me was 956.00 from Ford.  I couldn't stomach that.  So, i made a direct fit replacement that is reinforced in the correct places to not have that happen again.  I also include a direct replacement block off for the extra airbox that is affixed to the bottom of our CAI.  Why buy and aftermarket tube when Ford gave us such a good air system.  I added a picture of what I recommend to bond during install.  This can be found at any local part store.
