well, no and yes.. possibly maybe..
The width is already maxxed out at 3.5" thick. The length is already pretty long at 22".
If you were to get one that didn't have any part covered, it would have to be about 6" tall.
To get the same size core, you would need an FMIC that was: 29"x3.5x6" That would be a wideeee ass intercooler with the end tanks and everything. A 29"x6"x3.5" core would probably be about 35" total width with end tanks. Not sure how it would fit or not. I still need to come up with some easy bumper modifications with a duct to help increase my efficiency.. Taking on too many projects at once lately
It also wouldn't be anywhere close to a standard size core that you could just buy off the shelf WITH or WITHOUT end tanks. This means that you would need somewhere to custom make you an odd ball core which means $$$$$$ Then you have custom end tanks AND a custom core vs. just having to to custom end tanks (845 style) or using an off-the-shelf cooler (Turbosocks Style)
This is something that some other companies may address but you will also notice a higher price to go with the custom core size. Will it be worth the extra money? We will have to see.
The two kits available now use off-the-shelf sized cores that were the biggest you could cram in the space available without modifications.
There will be a crash bar coming out that will give you the ability to raise my FMIC kit higher to make it a bit more efficient..
All will come down to how much money you want to throw at the car and if you want to squeeze every OUNCE of efficiency you can out of it.
If you want maximum efficiency out of an intercooler setup, go with a water-air IC!
