They have a dry and filtered version. They posted something about their filters in the C219 CLS63 forum, but no one every responded.
for $40 it’s much cheaper than K&N or other options.
they protrude the same amount into the filter housing as a stock filter does, so it could be benefit from a spacer kit, (not what this thread is about, so please don’t start debating it) if you wanted to get the filter out of the airflow area.
I drove it afterwards and there were no issues, although it did seem to pull a little harder in the upper RPMs.
for the price it’s a much better upgrade than rhe K&N or BMS filters.
