Sorry I don't know the details of the IC in the pictures, but here is my shot at helping. You are probably going to have the best time doing one of these two:
1. Cut supports for the headlights and trunk latch to make room for the IC behind the bumper support.
I did this on my car and I like how it fits. I have Zenki and no fogs, so I don't know what challenge it presents.
2. Go with a High Mount IC like the
PBM variety. I personally think the HMIC is the best set up for an S14. A huge FMIC is usually overkill and with all of the piping it makes for slow throttle response. The major downside is you can't have AC with the HMIC.
