Anyone know the purpose of the vertical vent in the headlight cover? I haven't taken them off yet; just wondering where the air goes after it enters. Also, I was planning on getting the fogs (maybe), but if I wait a few years, will that little area be filled with bug and debris crud? Thanks.

haha.. yeah right.. you need some serious ducting to route air to the back of the wheel in order to cool the brakes. I haven't looked under the STi yet, but I do not believe they are there.
I think the vent is to reduce air pressue so the plastic clips do not deform and then you would lose the cover at high speed.

The covers pull right off...and behind them is a maze of nothing. Not for cooling...the what the bottom bumper holes are for. No one has found the mating brake duct covers as the MY02-03 WRXs have.
