I had an HKS Mushroom induction kit on my MY97WRX, and although I havent had any MAF sensor issues as apparently the MY97/98 mafs are quite robust. The induction kit was doing very little in the way of filtering, the ammount of dust I regularly cleaned out of the MAF housing was shocking. I have since changed my induction kit. The later MAF's are also prone to failure from vibrations passed through to them.

I've seen a car that went through a cloud of dust that was kicked up by the car in front (at Castle coombe). The car stopped dead as it killed the MAF sensor.
The filter.. HKS Mushroom..

Played with a car on the dyno as it was running Lambda 1 on boost, couldn't work it out (thought it was the pump to start with) Changed the Mushroom filter back to standard and voila.. proper fueling readings again.

I think you answered your own question.. change back to the standard induction box and fit a decent panel filter, It flows enough air for at least 400 bhp
