Being an STi originally, it only had the covers, no fog lights at all. I needed to get some WRX fog light inserts, then mount the trumpet inside. The one on the other side is for the oil cooler.
Using the old air intake just helps to direct more air where it should be. I have seen other people with this too.
The induction is an RCM product (K&N Re badged I think), front mount is an Autobahn 88.
