    Difference between aluminum and plastic SVHO intake manifolds

    Other than the difficult to remove ribbon on the plastic manifold and the weight difference, is there any other performance, distribution, or other differences between the aluminum and plastic intake manifolds?

    Only other thing I could think of would be heatsoak on the aluminum.
