Its on a single turbo setup. So the part with the little hole faces the filter or the part with the 4 slits? thanks

the arrow should point the way of airflow, so towards the motor, away from the front of the car.

What's funny is that I bought my car, and it ran fine at BPU++ level for 6 months, when I desided to do a hard pipe kit and by chance I notice that the MAF was pointing the wrong direction.

most of the time, more so with a hot-wire MAF it wont affect the engines ability to run with it pointed the right direction, but im suprised with the karmen-vortex that you didnt notice any driveability problems with it backwards.
