re: E36 Cabin air microfilter - Delete it?

[kevin@xxxxxxxxxxxxx (Kevin Lee)]

Dave,

This last summmer during the record heat spell we were having in the
Southeast, I removed my microfilter to increase the air flow in the car.
This dramatically increased the airflow, such much that I rarely use over
the 3 position for cooling or heating.  It reduces cabin noise and lets you
listen to the purr of your engine much better at a reduced fan setting.

No ill side effects yet for me or the car.
