    Excellent product BUT!!!!

    Published by Jean Noel on 15th Jun 2013

    Hello everyone,

    I was very excited ti install this product on to my 2013 ROUSH RS3 (Stage 3)...fit like a glove and it looks pretty sweet!! ROUSH product are very well designed! BUT..... Since I installed it, my air intake changed how my supercharger now reacts...in very aggressive acceleration whil shifting at high engine revolutions, the supercharge seems to be choking (hesitate)a split second... NIUT I can live with it does not change the awsome power os the RS# if not increase in but certainly 10-12 HP!! Enjoy this product!!!
