Hey all.  I have been looking at upgrading my intake and would love to try to go with a Ganza style pipe.  Problem is I have a MAF sensor on my 99 OBS.  I currently have a Spectre drop in filter and second filter in my torque box so it doesnt have an air leak.  Does anyone know if I could fab something up to locate the MAF between the torque box and TB? I wasn't sure if this would interfere with anything or cause the MAF to get too dirty.

I've seen it done on other cars (non-Subaru) by extending the wires for the sensor so they will reach to the throttle body. Then either cutting the flange off or using one of those adapters you can get at the parts store. Get the right size silicone boot to fit the MAF sensor housing round end to the TB. Then attach your intake tube to the flange end.

The MAF housing can be trimmed a bit if you need some extra room.

Seems to work fine.

I was thinking of doing this myself because I want to build a custom top mount airbox and make the outback hood scoop functional. Just haven't had the time or money to mess with it recently with school.

I really wanted to do that too but after some research learned to keep the torque box for sure! It makes a big difference in torque. But I wonder if it would be possible to keep it and still have room to put the maf after and a panel filter under the scoop.  Only when its not raining thought lol.

Here we go! Just add the MAF inline! 

That's another idea that might work better for these engines. I don't like the flexible-dryer-hose-looking stuff they have run around there but something could be made out of a more suitable material.

But I'd still rather it be a more direct shot into the TB, so I drew this up.  I want to do this.  I read that the purpose of the torque box is to store air for when the TB first opens. Well not much need for that if the system is so short and the box on mine would serve the same purpose anyway.
