So any of you 7.3 Powerstrokers who have done the CCV mod and are still using the round bakelite hood for an intermediate connection between your turbo intake tube and your air filter/box ( the round piece that bolts to the bracket on the driver side valve cover ) consider this. I got to looking at the piece and realized that the air hood and plastic step up was restricting at least 1/3 of the space,so I carefully cut out the restriction and lined it with a real thin sheet a aluminum and tape faced it with high temperture foil tape. Pictures enclosed.
