I was ready to get the UNI Filter for my NSX until I mentioned this to a buddy this morning (BMW guy) and he indicated to me that he has seen alot of discussion on the BMW boards from BMW owners that have put in oiled filters and have subsequently had to replace thier mass airflow sensors due to clogging at $300 - $500 a pop. I'm now a bit hesitant to go away from the factory paper air filter. I am not the most mechanically inclined but has anyone here had that problem?
