I went on Roush website and did an online chat with them and go nowhere :( does anybody know if the Fender Vents can be purchased from Roush or another source?
So I know its not a huge performance mod, but i figured I'd give a little feedback on what I've noticed so far.
IAT temps used to hover around 4-7 degress above ambient temps before this install around 70 MPH, now they are usually within 2 degrees. Above 90 they are usually equal...
