What size/part AIR DUCT to replace fog lamps?
 

A rock took out my foglamp over the weekend. Since the other lamp was already removed for oil cooling, I've decided to replace both "holes" with air ducts. Neither will have actual 3" duct attached (one will allow air to blow to the oil cooler, the other is a dummy).

After searching archives, I see most people are using either BSR or IO Port Racing ducts.

My openings are approximately 7.25"x4" with a bracket for the fog lamp in the middle.

What part numbers fit this opening best? How much modification will I be doing to get them to fit? Will I drill holes in the skirt and bolt them in?

i used the offset single inlet ones from IO Port, the smaller fo the two measures 3"x7.5" cut area and a 5"x9.5" area for the flange. What i did was buy a used carrera valence with the recessed fogs and did some cutting with a jig saw. I glues them with an epoxy, heating the ducts with a hair drier to get them to go convex and sit flat on the curve of the valence.

some guys inquired as to setting the flange in the back of the valence, i found that would have been diffucult to finish the outside edge of the valence. i just wish id had them painted with them installed in the valence. mine stayed black, took some heat here and i did not like it so much at 1st, it grew on me and the cooling impact was top notch.

Thanks! Looks great.

I'll post pics when I get mine in (it will take me a month as wife is expecting a baby in the next two weeks).

good luck, on the ducting and more importantly the baby.
