I've allways had the intentions of making the fog light into an air channel for the air box via inside the turbo side frame rail. Basically modify the frame rail so that 2inch or plus steel or aluminum or whatever ducting could fit through it and then cut a hole in the top of the frame rail. I think the best way to do it too is so that the edge of the ducting has some form or a large radius bent outwards. It would help increase air speed via whatever that science law of whatever states.

why have I not heard any talk of a vent in the bonnet like? has it got to be hidden or summick? and why is'nt there any vents in th bonnets of s2's anyway!? someone should get a second hand bonnet, put vents where they had them on the sport, copy it in fibreglass, give me one and slap it on! I've noticed they slow down too much when hot imo! have a look at my diagram I made on paint

hopefuly it will greatly reduce underbonet temps on the move and when in traffic, inturn reduce heatsoke
