    Are there any benefits to switching the IAT/ MAP setup to the MAF other than looks?

    I'm running my MS3 it IAT/ MAP and it works ok, but I'm always looking to make things easier/ better...

    I am doing it due to the restrictive AFM/MAF as I want improved airflow, which is also why I am looking to change the top of the airbox as the 1.6 square outlet is smaller than the 1.8's round, but it is impossible to attach a joiner pipe to this box as it does not protrude enough.

    This website details some of the restriction in the 1.6 intake tract. (it suggests that the afm accounts for 29% of the restriction)

    I can't find any literature to support my claims of a restrictive 1.8 MAF but I do remember one.
