I purchased Verus louvers because my IAT''s were bad. Wife and I autocross and being a 2 driver car, laps 8 through 12 really suffer. If you open the hood on your 16 and remove the liner you will see stamped indentations where they go. Make sure you buy legit louvers from a company that tests...
I won't assume to know your situation, however. We run in a crappy uneven parking lot, don't get me wrong, I love that crappy uneven parking lot. Is there a chance you and your buddies can find a space beg the owner to let ya'll put up cones and go for it? Just asking.
We've been looking into getting a cobb and a custom tune from PD. There is a transmission option we will most likely buy also. Talk to tuners. They probably have great info.
Sup dawg, coyote!
