If one is tracking his car occasionally, you'll find that heat in the brakes is a problem. This mod will help w/ additional air flow onto the rotor area while retaining the use of the fog lamps when not needing the air flow.
A couple of notes- I first attempted last year to setup the ducting so it was routed dirrectly to the center of the rotors- this is the most effective way to cool the brakes. Unfortunately I ran into a couple of problems- first the passenger side proved to be very difficult to route the ducting due to the manifold being in the way. Second I secured the ducting end along the tie rod and then attached it to the speed sensor bolt. I was never satisfied w/ this setup and came up w/ another one- this one's easier, albeit not as effective. The reason I used high temp 2" ducting was to help w/ my original setup- I also had to use a reducer on the duct itself -from 3" to 2".
This new setup you can use the lower temp stuff and in 3" making things easier and cheaper.
Let's get started- first the fog lamps need to be removed- three phillips head screws- don't try to remove the one that looks different- it's for adjusting the lamp. Next pull the plug on the lamps- now you can remove the fog lamp.
Should look like this:
