With all of the mods listed in my sig, I'm currently running the well known BHAF or DuraLite that's been mentioned already. When it comes to air flow, it doesn't seem to restrict or prevent whatever the turbo (S362fwm) demands as my motor is running very clean even when I'm mashing the throttle. Even the previous turbo (HTT Super 40/35 hybrid) seemed to get all of the air it needed as the motor ran pretty clean then as well.

I do need to put a pre-filter/outerwear on it though. I have the fitler mounted to the fender with a bracket I bought from Air Flow Systems. No shield at the moment to direct water away from it. I noticed a small amount of rust on the end of the turbo shaft at the compressor wheel which I don't recall seeing the last time I had the intake off. A little water in the intake doesn't hurt. If anything, it turns to steam in the engine and cleans some carbon build up out of the cylinders/head.



Here's what mine looks like with the above bracket.



And what's drawing the air through it. A BorgWarner S362fmw/68/12.
