I bought a SN95 Cobra intake because I thought it would clear the stock brace... I was wrong. I don't think they do a whole lot for handling, but they definitely distribute load in a front end collision.
I think Roush built it when the engine swap was done. Only reason I dont need it anymore is b/c it does not fit b/c of the Fox TB swap, the 90* Elbow is up to high and wont allow the brace to bolt down.
