One of the things I wanted to do on the modern hot rod build was I wanted to incorporate some carbon fiber. One place I felt like would be a good place to do this was on the intake manifold. I started by build a mold out of steel. I then used the vacuum bagging process to make the intake out of carbon fiber.
