All this housing does, in a nut shell, is raise the limp mode level of your car. SO say its 18psi, with the housing its now 30psi for example. If you are running at level and your not seeing limp mode, and your happy with the power you have, don't waste your coin. If your having issues with limp mode at lower psi levels, then its worth every cent.
For your car, this is the one you need....
