Hello there I'm wondering if anyone can give me a bit of advice. Im currently running an APS cai 65mm and want to get an FMIC however due to the cai pipe going through one of the two holes in the wing im wondering if anyone on here has an FMIC with this cai and has modified the pipework or cut a bigger hole in the wing to accomodate the pipework. I really don't want to lose the APS CAI.

Thanks
Matt

I have an APS CAI but use the APS FMIC, pic below

I was thinking of a cheaper FMIC than that one! lol so does the pipework on yours go through the other hole in the wing? Must be a tight fit.

yes mate, it goes through both holes, it is definately tight, but as you said the APS CAI is such a good bit of kit you should keep it, pretty certain loads of people are using other FMICs with the APS CAI??

Yeah I just found a previous thread from about six months ago where a member with a Japspeed FMIC asked the same question and the answers seemed to be 'you would need to modify the pipework' I was wondering if anyone has done this and has a pic of their engine bay? I know what u mean mate I def dont want to throw the aps cai away. Your not breaking your car are you mate lol first dibs on FMIC!!!

Japspeed FMIC will not fit with the APS CAI. I could have modded the FMIC pipework but could not be asked.

What about cutting a bigger hole in the wing?

Not possible because the way the the throttle body pipe sits with the bend makes it impossible for the APS to sit. Alot of fouling basically. The only way is if you modify the pipe or buy a different pipe. I got rid of mine but still kept the APS intake pipe. Take a look at the pic so it gives you a rough idea.

Start with your model and year and you might get some good information.

I don't regard fitting a CAK as a big deal when you have an FMIC. It is simply obtaining the right parts to move the CAK to where you want it. Silicon and aluminium tube or bends. There is no problem enlarging the inner wing hole with a power hacksaw or jigsaw and tidying up the edges, applying paint and then adding rubbing strip or door trim rubber and it looks like Subaru supplied the car that way.
The Hybrid HDi kits have their own cold air feed included in the kit but these complete FMIC kits are no longer available to me but I do have a number of the cold air kit on their own.
That said, once you get to higher power, 380 bhp plus I would not be using the CAK as you have to account for the additional inlet tract length and the fact that you cannot install a big enough filter in the inner wing.
See the Shaun Fennings thread in Projects "Starting Again......With A Hawkeye".
Shaun fitted a Hybrid GT2 from a Classic and as I predicted and contrary to some experts this showed good gains.
You need to read the thread forward from about page 15 but there is good information there.
If you are going for high power ie. 380 bhp up but more likely 450 bhp then you need the best intercooling possible with the biggest possible air filter which will be located in the inner wing and losses due to engine heat are secondary to the benefits you will gain. This can be further improved with a heat divider when the induction air temperatures will be the same as or lower than those from the inner wing.
