I'm about to fit a FMIC to my classic impreza, as a result I have had to fit an apexi Induction Kit in order for the FMIC pipework to fit through the engine bay.

I'm aware of the fact that the IK needs to be sectioned from the engine otherwise its going to be sucking in hot air, so option 1 is to build a small wall in the engine between the cone and the engine, however I'm not keen on this as its tricky to get a good seal, especiallly with intercooler pipework in there too.

I was thinking and came up the the idea of actually surrounding the air filter in a large pipe (sealed where the filter bolts to the MAF) and running this pipe off through the inner wing and down to the foglight as a cold air feed.
I have 2 questions:

1. Has anyone tried anything like this?
2. What would be the implications of doing this, ie too much air/not enough air getting to the filter. Would it be better to drill some holes in the pipe so that the excess air could be ventred into the engine through them?

Any help appreciated.

What about a internal wing mounted IK?

 

Are they available for pre 1996 classics and will they also fit with a FMIC?

 

Heat wrap your intercooler pipes and to keep the heat down

Slightly different from your set up but may be of use.
