whats wrong with some stock yellow ones? They look sweet.

 

No, you're reading it wrong. The arrows are force vectors, i.e. the direction the air pressure is pushing against the car body.

At the base of the windshield the pressure is towards the car, i.e. higher than ambient. This is pretty obvious when you consider than pretty much every car made in the last few decades has used that high-pressure area as the ventilation system intake. Haven't you ever wondered why air still flows in even when the fan's off?

No guessing is required. The pressure will still be positive and air won't flow out of the engine bay while the car's moving.

The only FC's with stock yellow fog lights were the rare Japan-only S5 Infini models. Your chances of finding a pair are very slim...

 

I also have a set of S5 fogs AND WIRING for sale $50 plus shipping

First one to paypal money to aserulneck@yahoo.com gets em.

 

when hooking up the s5 fogs on the s4 do i need the front bumper support thing for the fogs to bolt to or what? how would they bolt on to an s4?

 

^I have mounted S5 fogs in a S4 bumper before using the mounts on the housing and some angle iron from the hardware store. Then I just wired them in with a relay in-line.
